Ken, Thanks for the reply . The part about wristpin scoring cylinder has me sorta worried now . I checked all liners and none are scored , so I guess I'm lucky . Pistons look fine also . Talked to person I got motors from and he thinks he bought them new in mid to late 60's . Claims that none of them were ever taken apart , that he lost interest in c/l early 70's ,put motors in 2coffee cans and forgot about them until he heard me running one the other day. All parts are now cleaned, back plate gaskets made , some head gaskets will be put back into service and a few new ones made from beer cans . Guess I'm on a quest for wristpin keepers now .
