Just want to say the TwoManBand's explanation to clean the carb jets FINALLY SOLVED my problem. I was at my wits end. I'd rebuilt the carb, replaced the fuel filter, lines, primer bulb and starter switch. The machine continued to bog when I pressed the throttle. Using Twomanband's instructions, I removed the carb jets, cleaned them and replaced them. MAGIC! It works again. I can't thank you enough!

I'd like to give Mantis a Super rating! Back in early 1986, I bought my father a mantis tiller for about $300. He had had a heart attack and couldn't use the old large tiller anymore-he was 74 yrs. at the time. Dad passed away in '96 and I inherited the tiller! About 11 years later, the Mantis also passed away. I called the company about purchacing another, but wondered if I could get one that was easier to start than the old one. I had trouble adjusting the choke and at age 58, my arm got tired from pulling the starter rope! The wonderful lady I spoke to told me I could get an electric one that was more powerful than the gas model! I could also send in the engine off the old one and I could save $75.00!! I don't think the price of the electric was much different from what I paid in '86!! So, I got out my husband's tool box and got busy and mailed the part and my check and am happily tilling away today. I kept the edger that came with the original and use that on the flower beds. The only thing I don't use is the "kick stand" that came with the new one. I never seem to put the thing down once I get started!!
I want to thank Mantis for such a great product. They really know how to run a wonderful company and are very friendly to their customers. If you want a powerful small tiller, don't think twice, buy a Mantis! You'll be happy you did.

I inherited my Mantis 7222m tiller several years ago. I use it in a small garden for about 1 hour total each year. This year I experienced a strange problem.
It started fine - ran for about 1/2 hour. When I stopped to move some trash, the engin died and failed to restart. The plug was fouled so i assumed a flooding problem.
I went through all the maintence and it still wouldnt fire. I checked the plug wire with a voltmeter and couldnt get any voltage. So I figured it was a bad coil.
The next day I went to the garage to get my spade to do some hand tilling an decided to give the mantis a crank.
Guess what it started on first pull!!!! and ran fine but was ideling fast. BTW, the first thing I did was disconnect the kill switch.Could a coil revive itself after 24 hours sleep?
The Mantis is a fine machine, but the Orion engine seems to have some maintence problems.
Any comments would be welcomed.

I had a problem after running my mantis for over an hour. When I shut it down, it would start and run no more then 10 seconds. Remembering this is a 2-cycle engine, the first place I looked was at the spark arrester screen located under the muffler. Sure enough, It was plugged solid. No light at all looking thru. I removed the screen and used a propane torch to burn must of the residue off, followed by a light wire brush cleaning. After I reassembled the screen and muffler, I started right up and worked well for the rest of the season. Any 2 cycle engine may have this problem Chainsaws are notorious for this, Often the screen is removed and not even replaced. It is a 'safety???' feature, and runs fine without it. Hope this hint helps somebody. Happy Gardening!!

It seems that a lot of the problems people are having center around carb adjustments on the 2 stroke model. I've just finished some carb work to bring my used Mantis back to life and thought some of my experiences would be helpful to others.

The biggest cause of failure for small engines like this is fuel breakdown and clogging, and the most common place for this to occur is in the carb jets. I'm guessing that at least half of the problems reported here are entirely due to this phenomenon. Fortunately on the Mantis, this is a fairly simple maintenance item:

Find the carb jets, and remove the red and white limiter caps. Mine popped off with a little help from a flathead screwedriver. Under the limiter caps is the head of the jet, which will probably have a flathead screw head. On some of these Zama carbs, there is a knurled screw with no slot - these require a special tool which is available from a lot of places online.

No matter what tool is required, get the one that fits properly. Don't mess up the jets by using the wrong tool. Apply the tool to the jet, and run it all the way in, counting the rotations. Don't overtighten it, and when you determine the existing number of rotations, write them down. Then pull both the high and low jet all the way out. I'm not sure if they're different or not, but it would be best not to get them mixed up.

Now you have access to the jet hole. You're going to want to clean this - this is the source of the problem. I used some Carb and Choke cleaner (aerosol can with a straw) to dissolve the gunk and then blew them out with my own breath using a coffee stirrer. If you have an air compressor, that would probably be even better. You'll know you have them cleared if you squirt in another shot of carb cleaner and it dribbles through into air intake (behind the choke flap) If the air isn't enough to do the trick, you could try a thin wire. I'd start with a soft metal like copper, and only turn to steel if that didn't work. The carb body is aluminim (soft) and you don't want to scratch or nick the orifice with a hard (steel) wire. But if you need to do that as a last resort, it's still possible - just be careful.

With the holes cleared, reinstall the jets. Run them in all the way, and then back them out by the number of turns you counted before. If you don't remember, or if they were way off, start with both jets 1 and 1/2 full revolutions out - that should get you in the ballpark.

Since you've gone this far, you might as well replace the spark plug (check the gap first), air filter, etc.

Start the tiller - you may need a shot or 2 of starting fluid or carb cleaner at first if the fuel lines got air in them while you were working. If it will run a few seconds with starter fluid, it should suck the air through and start picking up fuel. You may have to do this several times depending on how much air was picked up.

You may have to start it with the throttle on, or some choke, or whatever, but once you get it running you can fine tune the jets.

Start with the high jet. Find a way to safely run the engine at high rpm's, and give it full throttle. Move the high jet in and out until the engine achieves max RPM's, which should also mean that it's running very smoothly and not missing.

With that done, return the engine to idle. A good idle is a combination of idle speed screw and low mix screw. Start with the idle speed, and let it out until the engine idles without turning the tine shaft. Or if it won't idle, increase the speed by running the screw in until it idles without dying.

Now check the throttle response - how well does the machine move off idle and accelerate. If it does well, you're done. If it hesitates, or bogs down, or stalls while you're doing this, adjust the low mix screw (probably by letting it out) until you get a good response. Letting the mix jet out usually increases the idle speed, so you may need to let the idle speed out some to compensate.

If the engine starts well and responds well but is smokey at idle, or fouls spark plugs quickly (black, tarry deposits on the plug), the low mix is probably too rich, and you'll want to run the low jet in a bit.

If the engine runs well but overheats or stops working after a while, the high mix is probably too lean (this will also cause tan or white fine-crystaline deposits on the plug) You can coorect this by letting the high jet out a bit.

When you're satisfied with the adjustments, pop the limiter caps back on the jet screws and you're good to go.

Understand that all of these adjustments affect the others somewhat, so make them one at a time so you'll know how to go back if something makes it run worse instead of better. Also, these adjustments are fairly sensitive. A quarter turn to half a turn usually does the trick.

You can avoid this exercise for the most part by using fresh gas and running the machine dry when you won't be using it for a while.

It sounds like a lot, but once you do it the fist time, it will become very easy. You'll also find that the majority of small 2 stroke engines work in much the same way, and are prone to exactly the same problems. You can use this procedure to tune many of them.

Happy Tuning, and happy Tilling!

I have had my Mantis 2-cycle tiller since 2007. I have had it in for repairs once. This year I went to start it and could not. I e-mail Mantis and got the standard reply. LOL
I called my repair shop and they agreed with Mantis that it sounded like cylinder varnish and wanted me to bring it it for repairs.
I started from scratch. I bought a gal. of new gasoline, fresh 50:1 oil and filled the Mantis. I could not get it to start. I finally got it to try and run, then flashed the choke several times while throttling the machine. Day one I could only get it going once for five minutes then nothing. Day two I was able to get it to run twice for five minutes each. Of course a lot of flashing the choke. Today I flashed twice and nothing. Closed the choke and it started and ran. I tilled 100 sq. ft. did a cool down run and shut it off.
I was determined that I could get it running myself and not have to take it in for repairs that cost $$$$. Shows that Mantis may sell their tillers but they don't always know how to get them running except repairs and more $$$.
Still all in all I love my Mantis. I bought it after trying to use a Troybilt pony. Mantis does a much better job.

Mostly I have loved my little Mantis, which I have had for 3 seasons, but have two significant complaints. First, the air filter nut came off and it is apparently a nonstandard size wing nut. Not finding one like it at any supply shop. Refuse to pay big bucks for one.

Second, and more important: there is/was a fault in the handle design. The kill switch is located so that if your tiller bounces even a little, your hand shuts off the tiller! Also, the handles want to flex too much, and pop loose the handle separator. Perhaps the newer models have fixed this.

I love the lightweight nature of this tiller, and it generally starts well. Had some trouble with it last year--had to have it worked on by a mechanic. But I, a person with moderate arthritis, can still use it pretty well except for the problems above.

I have had a non-Mantis little tiller in the past, from Sears, and it was a waste of money.

I have the 2 cycle tiller and for the first 3 years no complaints on starting or running .But now in the 4th year I was tilling my garden and it was working like usual but then it started bogging down so I clean the air filter and still bogs down. I took the filter off completely and still bogging down. It will run wide open when off the ground but touch soil and down it goes, no power. sounds like a chain saw with the chain stuck!
I took off the muffler and the screen was clear, checked the grease no problem there! The gas I was using was fresh and some of the same gas that was being used before, infact I put 2 other tanks full of gas prior to this thing bogging down!
whats up??? The plug is fine but I changed it out any way!

Bought a 2 stroke Mantis Tiller Jan 2009 and have used it 4 times (about 3 hours overall) with no trouble. Today I hit a foot long piece of duct tape which stopped the tynes dead. I cleared it with no great effort but now the tynes won't turn at all and I'm stumped. I bought the thing for it's simplicity and durability and I seem to have been wrong on both these points. It'll probably sit in the shed till I die or we move.

I have recently received a used 7222 Model 401702 tiller. It was stored with gas in the tank so, as apparently is typical from reading these posts, it won't start without some overhauling. Also it's missing the wire that goes to the start/stop switch. I will fix these things. It would be much easier with a real service manual which apparently Mantis does not make available (I did download the users manual from mantis.com). The lack of a service manual coupled with chronic failure to start is the reason for the negative rating. I emailed Mantis regarding the service manual and will update the rating if there's a reply.

Just repaired my neighbors Mantis tiller a 7222m, 2 cycle model. I think this is typical of most negative experiences I've read here. Fuel was left in during storage. as with any engine, gummed everything up. Cleaned the carb, changed the dissolved gummy fuel line filter and primer bulb, fired right up, idled, and revved as advertised. tilled my garden and it performed flawlessly. Finest garden tool I've ever seen.
Observation, when you store anything more than a month, ESPECIALLY 2 STOKES, drain the gas tank and run until the engine dies. Modern gas is worse than ever on lawn and garden equipment. Ethanol is a demon, it absorbs moisture making carbonic acid and eating everything aluminum and rubber. the gas part turns to varnish and plugs every little fuel metering orifice. Gasohol cannot be stored more than a month, never use old gas especially last years gas. Plastic gas cans and old antifreeze jugs are not gas resistant and add gummy nightmares to the mix as well. Metal cans for 2 stroke fuel will make your life so much easier. Be kind to your 2 stroke and it will be your friend. Bidding on an EBAY Mantis now, love the little diggers.

When the Mantis tiller is working its awesome, but my negative experience with starting it and keeping it running is similar to many on this post. I have never had problems with other 2-cycle engines. My $100 Sears trimmer uses the same gas (different oil mixture) and starts every time on the second pull (after choke). The Mantis is like a helicopter....plan to spend 2hrs maintaining it for every 1 hr you use it. Its not for a gardener, its for someone who enjoys tinkering with engines.

This spring will start the 21st year that I've used my Mantis Tiller for garden prep and lawn care. I can't imagine a more useful tiller, and I really like the dethatcher attachment. I've lent my tiller to friends, convinced others to buy one, and I've done a fair amount of charity tilling for neighbors. The reactions are almost universal: first, folks can't believe that such a little tool can do so much; then, as soon as they see it perform, they can't believe how wrong they were. I really think that using the Mantis Tiller is more fun than work. It doesn't always start on the first or second pull; but, it always starts. And, it always performs!

Thirteen years ago I purchased the 2-cycle Mantis. It was a workhorse. My neighbor borrowed it while I was at work and an elderly dying neighbor borrowed it from her and tuned it to his liking. It never was the same. Last year I purchased a 4 cycle Honda engine Mantis. I've used it three hours tops. It runs about 30 seconds and cuts out. The two local sales stores won't touch it. It should be warranty work. I have called Mantis several times and they won't help either because I didn't purchase it from their factory store. The least they could do is provide a service manual so I can trouble shoot. Huge waste of $450.

I had to decide between neutral and negative and decided on negative. Not that everything about the Mantis is negative, because it is a great little lightweight machine that performs well for small home gardening jobs. We have a Mantis 2 stroke. I have always been able to do my own tilling with it without my husband's help and actually enjoy using it. Even my 13 yr. old son could use it. It performed great for about 2 seasons, with me starting it myself. After that I had to have my husband start it because I just couldn't get it going. It got progressively worse to the point it just wouldn't start no matter the adjustments etc. made. We finally took it to a Mantis authorized repair shop. It worked the season after the repair and now it's the same old thing again. My husband does everything the manual says to do as far as mixing the gas and maintenance. We're not spending the money for another repair. I debated buying the Mantis 4 stroke with the Honda engine but I'm a little nervous about buying another Mantis. So, we've decided to just buy a new Honda FG110 4 stroke locally direct from Honda who can do their own repairs if needed (hopefully none will be necessary)! No more mixing gas, horay! And, it's only 5 more pounds so I should be able to start and use it myself.

I've owned a Mantis 2-cycle tiller since 1998. Since new, I've used Opti-2 synthetic oil with stabilizer in the fuel. Some years I've drained the tank; others I haven't. Regardless, it starts every year with about three pulls of the cord, whether the fuel's new or has been stored for eight or nine months. This year, the tiller started and idled as smoothly as ever, and I tilled the garden area with last fall's fuel. Two weeks later, I tried tilling a new area and the tiller stalled as soon as I tried to increase the fuel. Ten years' service with no maintenance is pretty good.

Now, I've readjusted the carburetor according to the instructions, changed the fuel & oil filters and cleaned the muffler screen. The same fuel runs great in the chainsaw, and the Mantis still starts and idles beautifully, so I don't believe it's the fuel, but I changed that for fresh anyway. Same thing: it won't take gas without gagging and stalling - acts like the fuel filter's clogged.

So, I bought a carburetor rebuild kit from the Mantis folks - they were helpful and the parts arrived UPS in the US in a timely manner. But, Mantis offers no instructions on rebuilding the carburetor, and I found this forum while searching for rebuild information online. I'm not a mechanical dunce, but I've never rebuilt a carburetor before, and I'd feel a lot more confident with some guidance. Does anyone know where to find an in-depth maintenance manual for this great little engine?

Overall, my experience with the Mantis is just wonderful. It replaced an 8-hp Troy-Bilt Horse that I used to beat myself half to death with every year, and the Mantis is a joy to use. I get far more work done with it with far less physical effort than I had to put in with the Troy - and with far less fuel. Troy's picture of "one-hand tilling" is something I never experienced. It actually threw me over the handlebars once. Give me a Mantis any day, even one that's misbehaving.

I have found the solution for the difficult starting and running of the Mantis tiller.
1. Use new gas with a high quality oil, I use John Deere brand.
2. Follow the manual instructions on adjusting the carb. I did this and now my machine runs just fine. Still a little hard to start, but it runs. That's all, simple. I do follow the storage instructions, and I also run the engine out of gas so there is none left in the carb.

I bought the Mantis tiller last year and have used it a lot. I love the little thing and call it "Mighty Mouse". The only problem I have is starting it, because I just can't seem to get the pull action right. If I have my husband start it first and let it run a bit, it's pretty easy for the rest of the day. I am in training to get better at starting it!! It's a great little machine with the heart of a giant. I have to remind myself not to try to use it for really huge tilling jobs... for those I hire someone with an industrial size machine!

I have run numerous 2 cycle engines for years from 3 cylinder 2 cycle SAABS, to Lawn Boy mowers chain saws and small trimmers and a Mantis tiller with a dethatcher.
Most of the people with hard starting problems don't say what kind of 2 cycle oil they are using or if their using the 50:1 mix ratio. This could be most of their problem. Some oils can do funny things to floats and passage ways in carbs when the gas evaporates out. Carbon based oils will leave waxes if allowed to stay in the carb with out gas. Even though Mantis says to drain the tank and push the bulb, I do not believe all the oil gets out and once the gas evaporates only the oil is left with it's waxes which harden up.
People that have trouble with spring starting may try Amsoil synthetic 2 cycle oil. Mantis says almost nothing about their oil as to whats in it or who actually makes it. Dealers have told me it's really Echo oil, it may be or not. In fact they don't even put the mix ratios on the little bottle. I don't believe it's a gas problem. I have an old 1978 mtd snowblower I leave gas in all year around and has never had a cleaner or even been apart. Always starts 2nd pull the next winter.
I haven't had any starting problems or running problems with my 2 cycle Mantis and just love the way it dethatches.

On April 8th, 2008, HUBS added the following:

Just an additional comment. Over the years I have left my gas and oil mixture in my tanks and engines and they have always started. I have not had one failure this way. On an old lawn mower I had with a Briggs engine I drained the gas one year and after winter it wouldn't start. The trouble was the valve stuck to the valve seat in the carb and couldn't move. After that I always left gas in the tank and carb and have not had any spring start up problems since.

I bought a mantis two stroke tiller just a month ago. After I bought it I read all the feedback on this site and was kinda bummed out as there was alot of negative feedback. My own wife laughed at me when it got here. She said it looked puny and said I wasted my money. Well she was wrong, it was money well spent. My soil is a DG type soil that is a bear to dig in, compacts pretty hard. At first it took me awhile to figure how to dig with it as it bounced alot. Well you just gotta slow the speed down, it will even loosen and move hand sized rocks outta your way. I double dug my veggie beds with it. So if your thinking about this tiller my advice is get it, do the routine maintenance, use fresh gas, and take your time learning the best way to run it and smile all the way to harvest. Thanks for a great product you now have a loyal customer.

A REAL GARDENING TIP:
If you want your tiller to start year after year (as well as other gas-powered lawn equipment, be sure to use a gas-preservative. I use it in all my equipment YEARLONG and everything starts, no matter how long it sits and even if the gas has evaporated from the tank.

I've had my Mantis Tiller 5 years. It did OK the first year as I tilled all of our flower beds and the edger did OK, too. After being stored during the winter - per instructions - it wouldn't start the following Spring. I was finally able to get it to go, but it would constantly die out. So I tilled and tilled and noticed that it took twice as long the second year as the first. I firmly believe what a fellow garden club member told me and that was that the engines used, even though made by Briggs & Stratton, are too small. There is no good reason to rebuild the carburetor every year and the engine every three to four. There are better things to do with your time especially after forking out $400 bucks for a machine that is supposed to be trouble free. I had a similar problem with a small gas Craftsman gas edger I bought. That was rebuilt after six months under warranty. That was the first piece of c r a p to get dumped. With the Mantis, I drained the gas and personally dropped IT into the garbage truck last Monday. My son bought a small Honda tiller four years ago. It has started year after year after being stored in his garage WITHOUT using Sta-Bil. I used it this year after cussing out the Mantis. The customer service people are OK, but all they offer is what is in the manual - verbatum. They're there because they have to be. Out of warranty? Oh well.

We've had our Mantis tiller for 10 years. I'll bet in all of that time, we've been able to actually use it 6 times--and 3 of those were cursing at trying to start it. Now the compression is about 33 psi. Customer Service says it is supposed to be 120 psi. With such little use, how can the engine be worn out?

I've had the carb rebuilt before a few times. I read on another forum that the carb manufacturer recommends an annual rebuild. If I get get a good used engine off eBay, I might keep it, else I will junk it and buy another brand.

Overall, I'm disappointed. We really didn't get the use of the tiller, especially when it was only ever used a few times in the Spring. When the company moves to offering its product with a Honda engine in order to stay competitive, that's a consideration.

My wife is the primary user of our Mantis tiller and she loves it. The issue I have, since I am the one doing repairs and mantainance on it, is the problem with obtaining parts.

I have part numbers from the manual but:
1. Mantis doesn't have any way to order the parts on the web
2. Their search engine doesn't even respond when you enter "parts" so even having p/n is of no value.
3. Even when you send email with the part information as a request for pricing they don't answer.

It appears that they are only interested in selling new units and once you have made the purchase there is no such thing as Customer Support.

The Mantis tiller is a simple, durable mini-cultivator. There are many similar machines on the market; Mantis has an edge over some of them with various aspects of its design, but they're all generally the same. You couldn't ask for a simpler, easier-to-maintain machine. If you think you need a degree in mechanical engineering to perform routine maintenance on a simple, tiny, two-stroke engine, then you shouldn't own a tiller, or any gas-powered equipment, for that matter. If you can't follow simple pictorial instructions and bolt a handle on a piece of equipment without installing it upside-down, stay inside and watch golf on TV. I've run my Mantis for years, torn it down and rebuilt it, and continue to use it almost every weekend- all without the benefit of manuals, advice, or a mechanical engineering degree. I'd be embarassed to post some of the comments I've seen if I were so inept I couldn't repair or operate what amounts to perhaps the simplest gas-powered device on the market. Mantis makes a good product that requires nothing more than common sense and basic tools to maintain. As in most cases, the biggest flaws in the product are incompetent, inept users.

I am giving a neutral because I have owned and operated my Mantis tiller for 3 years. It works exceptionally well, however, I did not look for any other produce before purchasing the mantis. My initial reason for getting this product was that it "weighs less than ten pounds." However, after my purchase, I found that at Home Depot, they had similiar weighted tillers for a lesser cost. If I could go back in time, I would not get the Mantis, I'd go to Home Depot where I have always had great success.

I have owned my Mantis Tiller for 9 years. I have worked this little machine to death. I use it to maintain a 60 x 40 garden & also use it to edge all of my planting beds, sidewalks, driveway & brick paver walkways. This tiller goes until I can't take anymore. If one does their own basic maintenance- such as spark plugs, grease, shot of carb cleaner now & again. It will run trouble free. With the type of carberator system that this tiller has, the oil & gas mix must be fresh & properly mixed. I use a 50-1 mix, keep the air filter clean & have no problems in starting or running, I find it very easy to adjust the carberator by turning the adjustment screws. I believe most of the problems that people have are fuel mixture related, as my Mantis never fails to answer the call.

If you are considering a Mantis Garden Tiller that uses a two-stroke engine, please be prepared to go to school for mechanical engineering to perform the maintenance the Mantis requires to keep operating. This garden tool gives me bad dreams when I know I have to use it. If maintenance is performed to the letter, it may start up and run for you. It may NOT. The customer service people at Mantis only know how to tell you to take it to an authorized dealer, or send it back to Mantis and pay the freight. The two-stroke fuel and a finicky carburetor is the primary culprit to keeping it running. There are other issues, but the fuel and carburetor is the worst. Gasoline must be fresh ( I have never seen an expiration date on Gasoline) or it will gum up the carburetor and will not start. Don't even THINK about adjusting the carburetor as it takes an expert to do this. The owner's manual is very ambiguous about this. This tiller is the same as the Echo version for your information. If you can keep it running, it's a great garden tool. I gave up on mine and gave it to my Son-In-Law who is a mechanical engineer by profession and he also agreed ithat maintenance will cause you heart aches.

The Mantis tiller is one great garden tool if you are a mechanical engineer specializing in gas engines. The Mantis works well, when it runs. It is a maintenance nightmare to keep it operating. For one, it is extremely tempermental. You can't use gasoline older than a few weeks old ( how many gardeners keep gasoline in the shed for weeks & months? see what I mean) You have to "drain" the fuel tank after each use and completely "dry" out the carburetor if you don't use it for a few days. The fuel system clogs up if it sits for more than a week. Trying to read the owner's manual to keep up with routine maintenance ( the Mantis is ANYTHING but routine) requires a PHd in physics and mechanican engineering. On the plus side, IF you can keep the Mantis running, it's a great tool.

As a dealer of Mantis Tillers I would recommend that users of these little workhorses use only fresh gas that has not been out of the pump for more than a month or so.
The fuel formulations that we are forced to use in the northeast derive their octane from ethers that evaporate quickly. I have the best luck with storage if they are run out of fuel. Do not store the tillers with fuel in the tank. This will assure that the carburetor and fuel filter are not gummed up when you are ready to use the tiller next time

Little beauty is four years old and still works like a charm. Each winter I leave it in the icy garage, and each spring it starts right up using last year's gas. It has never been serviced, and does everything it was advertised to do. It grinds through the worst clay as easily as through the sandiest loam.

When I bought it, the rep was friendly and knowledgeable, and it arrived quickly. And the company has never bothered me unless I initiate contact first.

Purchased tiller on line ,new in the box never used, but not from dealer. This is its second season used for our flower gardens and a (small) vegy garden. I thought it was the perfect m/c until it seized a connecting rod bearing this weekend. I have owned a power saws for the past 30 yrs. which were used every year to cut up our winter's wood and have never had a 2-cycle seize like this. I also own a homelite weed wacker which is a 2-cycle, and it is 8 yrs old and still runs strong, so mixing fuel is not an issue.The Mantis company will not sell me the parts I need for repair because I live in Canada. Referred to an Echo distributor who in turn referred me to a repair shop in my home town.Priced the part. (# A011000210) $290 can + tax. A new motor according to Mantis is $150 U.S. but they will not sell to Canada. I am now seeing a whole different picture reguarding the Mantis Tiller. Lots and lots of sales but no way to buy parts at a far and reasonable price. Infact I don't even know why they come with a parts list. So here I am looks like new but will not run. Maybe I will sell the good parts on E-bay and recoup some of my money. What are my other options so far ????

Back in early March I ordered an electric Mantis cultivator direct from the Mantis people. They said it was back ordered until the end of March due to a part the production department was waiting for. I received yesterday (4/10/06) a letter saying now it was still backorder and may by shipped April 27. I called Customer Service and they said their production line is still down - no part. I cancelled the order as I am afraid if I needed any replacement parts, the same story might ensue. Doesn't it seem strange to have your production line stopped for 2 months waiting for a part - where is it coming from? Mars? It just doesn't seem like a reliable company to me. I don't think this rates a negative review as I have not had the opportunity to use the product. But the Customer Service Dept. did not try to persuade me in any way not to cancel or nor did the gentleman try to convince me to switch over to their gas model. His attitude, although pleasant, was "fine - cancelled - have a nice day." There was no attempt to keep me as a customer. So I guess I'll check out other cultivators - maybe someone of them want my money. Too bad - I was looking forward to that little Mantis!

my mantis when it starts works great but it has been a hard starter all its life...I'll bet I have spent $200 on service trips/bills to local repair shops...these two cycle engines seem to either run quite or some are hard starters all their life...my experience...I think I'll call Mantis tomorrow after having trouble with it bogging down today...

My experience with the Mantis tiller has been very good.

I've done extensive sod-busting and created several large gardens under less than ideal conditions, and the tiller is a workhorse that has never needed repairs in eight years. It is easy to use, though it does take a firm guiding hand in heavy clay soil (and if used for long periods to break sod, you might vibrate for a couple hours afterward ;).Excellent machine.

I ordered directly from the company and had a good experience.

Bought my Mantis, but didn't use it for 3 years (unfortunatly)...When I did, it was one BIG disappointment...I use it because I have to...haven't had the starting problems as much as some, although does seem to be getting harder to start...the Throttle is a MENACE...when you hit a hard spot or something hard, the unit starts to bounce, thus you tighten your grip and the throttle speeds up, making it MORE dangerous...maybe it's all me, but can't control the speed, when tilling, using the back & forth motion, still piles EVERYTHING up behind it, instead of digging it into the ground...I have planter boxes, so when I get to the end, it leaves a big hole...tines aren't suppose to break but have broken one or two...
The Edger isn't even a joke...save your money...the crevice piece is non-efficient...does a somewhat job, only...
It was one of the BIGGEST WASTES OF MONEY I have ever done....learned the hard way....I will NOT ever recommend them to anyone...
the unit is NOT EASY for a "senior" to use....I have a large tiller that is just as easy to man-handle as the Mantis...for the price, buy a large tiller.....not that much difference...
The Mantis tiller is, OVER RATED, OVER PRICED & LOUSY....
Company representative comment on November 23, 2005:

Dear Doughead:

The Mantis Tiller comes with a one year from date of purchase money-back guarantee when purchased directly from our factory. We'll even send UPS to your door to pick it up, as long as you box it up.

In addition, our tilling/cultivating tines come with a lifetime guarantee against breakage. Should a tine break, all you need to do is ship the broken one back and we will replace it at no charge.

The Mantis tiller is designed to be used in a simple back–and-forth motion, however if the tiller is kept in the same spot, with the throttle pressed, the tiller will absolutely dig a hole and if the loose dirt is removed, a deeper hole can be dug.

As with any new piece of equipment, it takes a few practice sessions to get the full benefit from it. Using a lighter touch on the throttle, and taking smaller “bites” will lessen the bouncing.

The Border Edger attachment, a free premium with a factory-direct order, is designed to make a more defined edge between any pieces of landscaping. The edger becomes more defined and neater with frequent and continued use of the attachment. The Border Edger attachment is not designed to cut overhanging landscaping or trim back overgrowth.

Any of our Customer Service Representatives would be happy to discuss the tiller operation with you; however, we have no information on how to get in touch with you. Please call us at 800-366-6268 Monday through Friday from 8:00 a.m. to 5:00 p.m., eastern time.

We would like the opportunity to help you.

I have owned a mantis 2stroke and 4stroke tiller and both have been great machines-I have put them to the test working 8hr days with only a few breaks ;) Very easy to start and use. Light weight and easy to operate. Great machines-i prefer the 4stroke myself.
I also own a little wonder lawn vac its a great machine. Powerful turns the yard leaves and branches to mulch or compost material-easy.
Had no trouble with a mountain dew can or plastic butter dish!
***keep toes and fingers away from suction area***

I WOULD HIGHLY RECOMMEND MANTIS.LITTLE WONDER PRODUCTS!
