I got the SFX 110, has the 108 cc engine. I cant get this thing to stay runnin'. Any help would be appreciated. i changed the oil, took out restrictor plate after break in, changed spark plug. It's warm here now about 90, so its not a cold start thing. It takes forever to warm up still w/ choke on. After about 2-3 minutes finally will idle will choke off. Then just dies. Sometimes never to restart again, or maybe will start, and work for 20 minutes then die, an almost impossible to restart. Uggghhhh!!!!!

 

I'll presume the carb has been cleaned well. Then I guess I'd check the compression, then I'd check to make sure the timing is correct (ignition and cam timing).
Providing al that is OK, I feel it's electrical (CDI/Coil). To be honest, this is where I feel the problem is, but everything needs checked.
Good luck.

 

I havent cleaned the carb yet. I should of stated, i only have about 6 hours run time on this thing so far. I wouldnt of thought it needed a cleaning so fast. I'll try that. Thanks.
