Check the carburator, it sounds like a main jet is clogged or the carburator is dirty. Is the air filter clogged? Is the motor under strain?

Starting manual for mantis


all of the mantis tiller manuals can be found here:
http://mantis.com/mantis-owners-manuals.asp
just pick out the appropriate one and away you go.

as far as starting it goes, make sure the switch is set to "I" and not "O" (top handle.) be sure you have gas in it, pull out the choke knob (front of the tiller) and depress the bubble once. pull the engine cord until the machine tries to start, then push in the choke and pull again - the engine should start within a couple of pulls. let it warm up before you try to do any tilling, and you're good to go!

Just bought an older Mantis 2 cycle tiller. The tines engage when the tiller is started. Of course that makes it hard to start with the tines on the ground! I don't believe it was doing this when I...


if the idle is too high the tines wont stop due to the tiller tines are run by a "centrifuigual clutch" which means when you increase the throttle speed the tines will start to turn : there are 2 adjustments you can try,1) adjust the idle screw under the carburetor where the throttle adjustment and a triangle piece of metal touch(your throttle cable wire will be attached to this triangle) ,if the triangle and idle adjustment don't touch and there's a gap between these 2 pieces close the gap by adjusting the 10mm adjusting nut,this will correctly set the idle #2) adjust the idle adjustment screw talked about above till the tines dont turn with throttle set at idle or lowest speed setting

After the tiller will not achieve high RPM nor sustain it.


Watch this video. Also, before storing or not using mantis for a while run the carburetor out of fuel first. If stored with fuel and difficulty starting after a prolonged period of non-use add an ounce or two of 100% acetone (available at walmart) to your fuel tank.

Tines turning, mantis 2 cycle tiller


sounds like a piston seizure. are you using correct oil and ratio. carb could be going lean and causing the cylinder to over heat, adjust high speed mixing screw and hope no damage has resulted.

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.

Does not work on high RPM


sounds like its over heating. be sure all cooling fins on engine are free of debris. your carbeurator may also be running to lean which will cause over heating.
