Hello eveyone. I'm working on a problem today with my Lifan LF50QGY with the 49cc horizontal engine. I believe the cam chain tensioner is locking the motor. When I pull the cam gear and tug on the chain I can spin the motor freely. I'm stuck on removing the flywheel to inspect the cam tensioner mechanism. I spun the center bolt off but can't remove that @#$%^%% flywheel. Youtube videos always show that coming off easily. Anyone know a technique other than brute for prying? What about those allen head bolts that surround the center nut and the main shaft. Do they need to come off?
