Well I was using my plane in low throttle, driving it around to get a feel for it, and the engine all of a sudden stopped and wouldn’t start using a my electric starter ,which could not produce the necessary force to turn it over. Is there anyway a lean low speed needle setting could seriously damage an engine or is the starter damaged cause I can still turn the engine over by hand ?Oh and i leaned it to the point where sudden acceleration would not stall the engine, i didn’t make it lean as the limiter allowed. Oh and i have an evolution nx 1.00.
