RE: Official Jammin X1CRT Thread
So the engine is new or used? Try Spinning the flywheel counter clockwise with your hand. Is it easy to turn the engine over with your hand? To me it sounds like your engine has lost compression. But the engine should have last for a few gallons, not just a half gallon. If that's not it, it must be the carb. Go back to the factory settings and try from there.
