Looks like I have missed a lot on this thread in the past few days….
First, Bill is absolutely right, good compression readings do not guarantee all is right with your powerhead.
I am confused by all your pictures and postings at this point. You have several pictures of horrible looking scored pistons with jammed rings. Needless to say, these parts are not usable and can not be "repaired". The corresponding bores are surely damaged as well. My question is which powerhead did these pistons come from? The original blue powerhead, or the replacement white powerhead? Or, do both powerheads have bunged up pistons and bores?
