Question about Mantis 2-Cycle Tiller
Will not idle or stay running when it does it want run smooth has low hours on it i put a new carb kit in it but dont know the setting on fuel mixtuer screw
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: Won't stay running...
I had the same problem with my mantis. It would start fine after a few pulls, but had no power. I changed the plug, replaced the carb completely...nothing helped. Took it to a shop and paid $70 for a tune up that didn't help at all, and the shop owner just said "sorry".
After everything else was done, I pulled the cover off the muffler, (3 screws) then removed 3 screws over a small spark arrestor screen and found it was clogged...cleaned it and guess what...IT WORKS FINE NOW!
The best and easiest fix I have ever done to a small engine. I felt like an idiot, because the exhaust side of the motor MUST be clear to work properly on small engines. The only reason I was removing the muffler in the first place was to check the compression and VOILA!!!
An easy and quick fix I recommend for all Mantis tillers before you waste money on carb issues (which is what the company will tell you to fix to solve this problem).

Carburetor problem. Two stroke engines use oil mixed with gas. Old fuel or setting over the winter will cause varnish and sludge in the Carburetor. Start by buying a can of carburetor cleaner and mixing a new can of fuel.
1) Dump the old fuel and check replace it with new.
2) Remove the air cleaner.
3) Pump the prime bulb 3 or 4 times, set the choke, spray the insides of the carb with the cleaner and then try and start it . It should sputter and run for a few second but chances are it will take a few sprays to clean the jets

My name is Dane and I am going to assist you in solving your problem.
You should have an idle screw adjustment on the carb to adjust the idle RPM. As you pull the trigger, watch on the carburetor for a small moving plate. The idle screw should touch that plate. Be very careful, and have someone hold the tiller and start it. Back off the screw just enough until the tines stop turning. I hope I've helped. If you found this reply useful, please leave me some THUMBS UP, if you feel I've deserved them. Thank you! Dane
