What is your proper mixture?50:1?
Be sure you are mixing 2cycle oil to 1 gallon of fuel or whatever it takes to make this ratio
My reccomendations are run 40;1 3.2 OZ OF OIL TO ONE GALLON OF GAS
also you may have a lean out condition and the H on the carb, may need to be ritchened a little

Motor should not be screaming you should have a slight blubber when throttle is held wide open

Starter rope hard to pull on mantis tiller


Sounds like your engine may be seized up. Mine did the same thing and I had to replace the block. If any dirt gets past the air cleaner or if your fuel mixture isn't right it won't take long to lock it up. If you need info on where to find parts, let me know. Good luck.

I would like to know what the factory high and low settings are on carb mantis 2 cycle there are no plastic caps on my jet screws and need to know how many turns out ...


After seating the screws back them out 1 1/2 turns. This should be close enough to get it started. Let the motor warm up a little then, with it idling, turn the low screw in until it starts having a hard time running then back it out until it idles smoothly. Prop up the Mantis so it can run at full speed safely while you adjust the high side. With the throttle wide open, again turn the high screw in until it starts running roughly and back it out until the motor is running smooth. Some say to turn the screws out until the motor starts having a hard time running and then turn it back in half way to where it was running bad at the other end. This doesn't work as some engines don't care how far open the screws are.

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 have a Mantis electric cultivator that won't start. it's only a couple of years old


Electric tiller, and it will not run ?
I would check the cord that you plug into.
You must remove the plastic housing, by removing the screws.
Next look at the plug, is it in good shape, has anything been pulled out of it ?
The motor brushes should also be inspected.
Please let us know, we repair all Mantis equipment.

Difficulty starting Mantis tiller & keeping it running


dirty carb or old gas or plugged air filter or combination of all three. give it a good clean up and some fresh gas.If you are not up to cleaning up your carb you can buy a cleaner lube additive that will work pretty well if you can get the machine running. You just add it to the gas and it helps clean things up internally as its running.
as a tiller has to work in the dirt you always have to spend a few minutes cleaning things up to avoid the bigger problems.

Wont run, not getting fuel. disconnected fuel filter, still nothing. Can spray a shot of carb cleaner directly into carb, and will run until it burns the fuel then dies. Check and getting good spark.


you say it's not getting fuel? when you bypassed the filter was gas coming out of the fuel line right where it connects to the carb? If it runs on ether, carb cleaner or pouring fuel in the carb then your problem wont be the the carb or motor it will be something like a cracked, dryrotted or pinhole in the fuel line. Or something restricting the flow from the tank to the carb.

Mantis tiller stop working. I was tilling my garden and it completely stop. I try to sart the tiller but the puller cord wouls not move. Took the pull cord top from motor the pull cord assembly was working...


OOOPS...this sounds bad, like a locked up motor. If it is a 2 cycle engine it is especially bad...and it probably is toast. Take it to a shop and have someone check it out, but doesn't sound good..Sorry
