Oh, oh.... You might be right. I just tried turning the flywheel with the engine cold and although there is some resistance, it is light and then goes to TDC where it has the two "clicks" before coming back down to BDC. I just compared it to my new vx18 engine that has never been run yet and that has a lot more resistance than the vx16 has now. Should this broken in vx16 motor have just about the same resistance on the flywheel that the new vx18 has that has never been run yet?
