My pistons, cyl. walls, clearances are good. I just want to lightly hone and replace rings. On three of my pistons, the top comp. ring was stuck in the ring groove and required some less that gentle persuasion to remove them. (in other words, little pieces of ring) Now I'm looking at my options as far as the mail order/internet suppliers are concerned, and I'm finding myself scratching my head alot. I think I'll go visit my friendly Bumper to Bumper who is a Sealed Power dealer and see what he has to tell me.
