20 Most Recent Mantis Gas Mini Tiller/Cultivator, 2 - Cycle Questions & Answers

check to see if cable is in one piece, not broken! look down where it hooks to the engine while accelerating, you should see a lever move on engine, if so then it may need the accelerate adjusted!

-Replace new one. Good luck mai

Check the exhaust side of the tiller. There are 3 screws on the muffler cover that need to be removed, then there is a cover on the spark arrestor that also has 3 screws to remove. Inside this is a small screen (the spark arrestor). Take it out and clean it with a good solvent (I use carb cleaner). This is the easiest and least expensive fix.

If this doesn't work you may need to rebuild the carb. I have found it is easier and costs about the same thing to just replace the complete carb.

The company will tell you to make sure you always run the carb dry before storage, but I have NEVER done that as I believe it dries out the gaskets. I just use STA-BIL gasoline stabilizer before I store it for the Winter and keep it setting level in storage.

hello sir, Please provide the following information so that your issue may be diagnosed properly,what is it? brand name,complete model number The problem, What is happening with what? When it is happening? Are there times it does not happen? Did it just start happening? Did it ever work ? Did any seemingly unrelated event coincide with whatever it is not working? need the model number and brand name, if you need a manual i need the brand name and model number,if it is a riding mower the model number is under the seat.a snow blower the model number is on the rear of the machine, let me know,thank you. 44

Make sure there are no leaks in the bulb. Did you reattach the fuel lijnes correctly? You should feel resistance after pushing 3 or 4 times to ensure fuel is getting to the carb. If necessary replace the bulb. Otherwise check with Mantis at www.mantis.com or give them a call for troubleshooting assistance.

I would say it is the coil, if you have a multimeter you can connect it to the coil and try to start it to see if it producing voltage. Hope this helps Tim

Parts breakdown. You should be able to do it yourself.

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.

do a fuel system overhaul...but always w a 2 stroke pull the muffler and inspect the piston and cylinder if its not scored and you feel good compresion most likley its your fuel system. if it is scored it gets metal to metal and the hot metals expand.

YES sure - just locate a dealer and get them from them. They might even replace them free on the labor.

Thanks

yes sounds like it may be a clutch problem. go to mantis web and there go to dealer locator's type in your zip. most small engine shop can help you. good luck

I make one with tin snips and a tin can or sheet metal from an air duct. Make sure you have the ring with the right side "UP", the beveled edge (if there is one) goes up or toward the head.

If your Mantis has a ZAMA carb, replace it. Don't bother with a carb rebuild kit.

I had exactly the same problem, did everything you did. New carb fixed it. Runs like new now.

If you look inside the gas tank, there is a small little gas filter attached to a small plastic tube.
Fish the gas filter out with a small wire.
Replace the filter with a new one.
Please let me know if that works.

I would pull the tines off of the transmission. You probably have some debris wrapped around the transmission drive shaft(s).
Please let me know.

THAT COMES AS A ASSEMBLY, GOOGLE FOR NEAREST DEALER

Have you checked the spark plug and see if its clean and also check the fuel line and carburetor for clogs. And you can also check the air filter.

Hope you find this helpful.

the fuel line may be clogged or is collapsed go to a car or a home improvement store go to lawn and garden and get a 3-4 mm gas line

You have nothing connected to kill tab on the ignition module? The module is asymmetrical so it can't be installed backwards.Measure coil secondary resistance of both original and new module. I don't have the exact spec and range can vary widely in small 2 stroke.Are there any calendar dates on it... not finding the model as Mantis.Comment for further assistance.
