Flywhee; FREE PLAY
I just bought a used Sirio .12 engine and when I installed the clutch and turn it around with my fingers there's at least 1/8 of a turn free play when the piston is at TDC. That is when the piston is at TDC I can turn the flywheel backwards and forwards 1/8 of a turn and the piston doesn't move.
There must be a problem with this engine and I don't want to start it in this state. HELP PLEASE?
