Opps, I forgot to mention that I pressure tested and it is golden. Not a drop at all in both pressure and vac tests. I almost think it was something to do with the fit of the piston. It never felt quite right even when brand new (Meteor piston on a 036 cylinder, which had never been cleaned up). I got the saw from Wes (scored 034 with torn intake boot) and made it into a 036. So I'm thinking cold seize (highly doubt it) or piston fit problems. Everything else looks and tests out to be fine.
