Tommygun,

Thanks for the advice.I am having that very problem with the motor sticking when the piston is at top dead center. In fact, I can't even pull the damn string. Make things more problematic is Ican't set my gear mesh up properly as the motor locks up so bad that the spur gear will not turn with the wheels. Getting a piece of paper through there is pretty difficult.It takes a lot of force to "unstick" the piston.

Are you suggesting to go through the break-in process will ease up this tension and relieve some of the pinch?

Or am I dealing with a situation where I just need to start the break-in process or should I start thinking about going back to the hobby shop to return the motor.

Thoughts?
