Hi all,
My engine is new with maybe three tanks through it. The pinch to me is right where it needs to be for a new engine. First start is always good and it runs great. Second start the piston will give me a hard time locking up at the top....I mean real tight. Removing the head will free up the piston.
In the past I've had engines(various ABC engines) that tightened up with head on and some that lost their fit with the head . Never new why or how this was happening. I would love to Know why.
Should I just run it on the bench wide open very rich till it loosens up?
Thanks, Chris
