SOURCE: Mantis Tiller

check the fuek lines for hole and leaks, check the fuel filter and clean if necessary. remove the carbuerator and inspect the gasket; it should be soft and flexible, if it seems hard or brittle replace it. clean the carb with carb cleaner sray (available at any local auto parts store) and compressed air. make sure you get inside the small fuel rail holes. check the primer bulb for pin holes and seating/sealed properly. if that doesn't work have the carb repaired at a service center or replaced.

SOURCE: mantis tiller 2 cycle seemed as if it was running out of gas

Check fuel filter and lines, if thay are good I would get a carb kit and set the adjustment screws at 1 turn out from lightley seated to start. Don't lean high speed screw too much.
You might check muffler & cylinder port for carbon first.

SOURCE: Mantis 2-stroke tiller won't start

This could be one of several problems...
• Last year's fuel. Get some fresh gas.
• Every 2-stroke needs a new spark plug each year... you know what that means.
• Clogged carb jets due to storing the tiller over the winter with fuel in the system. Never, ever do that. Now you'll need to pull the carb apart and clean it. Most of the orifices are so tiny you can't see them. Good luck.
• Engine is so old the crankshaft seals have hardened with age. This is one reason no 2-stroke lasts longer than about 8 years. If the seals are shot, then it will cost more to fix than a new one costs. Time to toss it.

SOURCE: difficulty adjusting carb for smooth idle and full power tilling

Your quickest fix for this problem is to simply replace the carburetor, a Zama K54A. Do it all the time. After that, if you can find a 2 cycle oil, Opti-2, it's the best you can use and it's a one mix for all your 2 cycle equipment (blowers, trimmers, chainsaws, etc.) It's the only 2 cycle I sell in my shop.

SOURCE: trouble starting old Mantis tiller 9012 - don't have a manuel -

Mantis has the owners manuals in pdf format available for download on its website. The tillers are here (I hope the link to the tiller group works...if not, just go to the main site and look for "owners manuals" link.

Also, you can call a number and get a representative who usually can help at the numbers listed there, find authorized service people if its not something you can do yourself, order parts and find detailed schematics in the owners manuals. My dog actually ate mine. LOL. But they are free, the owners manuals, unlike other places that charge you for them like they were a "part".

Can not find my manual for the mantis tiller..forgot hot to start it up for the first time


You should be able to go to the Mantis web site and download the owners manual. To start, make sure the switch in turned on, push the fuel primer bulb several times (until you feel resistance), pull the choke out all the way and pull the starter rope until it fires. Then, push the choke half way in and it should start. Let it run a 30 seconds to 1 minute and then push the choke all the way in. Be sure you are using the currect fuel/oil mixture with fresh gas and oil. If you have not done so already clean the air filter and replace the spark plug at the recommended interval.

We purchased a mantis 2 cycle garden tiller new and have only used it 3 times. it has only been used maybe 1 hour total and now it wont start at all. what can we do to get it to start?


Empty mantis fuel tank. Remove and check spark plug. Replace with Champion CJ8Y or NGK BPM7Y if necessary. Gap is .6mm - .7mm or .024" - .028". Prepare fresh fuel/oil mixture. Add fresh fuel to tank along with 2 ounces of 100% acetone (available at walmart) - this will remove deposits inside of mantis from sitting for prolonged periods. Try to start several times. If unsuccessful let mantis sit for a while. Do this several times if necessary. Eventually it will try to start. If it will not remain started then you are successful in completing the previous section. Next you need to watch this video and do what it says. It is actually quite simple.

I did a tune up on my mantis tiller, plug, air filter, fuel filter, carb adjustment, the darn thing idles but want throttle up, is it ready for the trash,,,,


It is easily remedied. Watch this video:

http://www.alamia.us/mantis_parts_s/148.htm

Also, always run mantis out of fuel before letting it sit for any period of time. If it does sit, put a couple ounces of 100% acetone in the fuel tank (available at Walmart) with some fresh fuel/oil mixture. This will remove the varnish inside the tiller.

One screw is fuel and one is air, try turning the screws in all the way then open three turns and start from there.
