I have a four year old mantis tiller with a two stroke single cylinder engine with a ZAMA diaphragm model C1U type carburetor. After using the tiller for a few hours this week the gas supply cut off. I removed the carburetor and using my compressor blew out all openings and took the gas filter off as it appeared to be dirty. After re-assmbly I attempted to start the tiller, however now it started to flood the engine wetting the spark plug which is new. After letting the tiller sit over night with the spark plug out and purging the combustion chamber I re-installed the spark plug, put the ingnition switch to on and tried to start the tiller without using the bubble purge or the choke. The engine started with on pull of the cord ran for about ten seconds and stopped. I took the spark plug out and it was wet with gas. I bought a carburetor kit from Mantis and a new gas filter and installed both after cleaning the carburetor throughly with gum out. The problem still existed. I once again cleaned the spark plug and after purging the combustion chamber and cleanin the muffler system, I re-installed the spark plug, cut off the gas supply to the carburetor and restarted the tiller it ran great with the gas that was still in the carburetor, I cut off the ignition switch, cut it back on and restarted the engine it ran for a few seconds until the gas ran out. I unclamped the gas line, let in a small amount of gas to the carburetor then reclamped the gas line, dried off the spark plug, started the engine, it started right up and as it ran I opened the fuel line and it flooded out immediately putting me back to square one. Only two items were not replaced, the Main Check Valve Nozzle in the caerburetor, and the Check Valve that comes out of the gas tank. This really has me stumped. HELP, Bob

I am trying to replace the starter rope on this and I cannot get the Clutch Drum Assembly off. Does anyone know what sort of tool I need to unscrew it?
