Re: Missing my top piston ring retaining pin!
every engine i ever built never had pins holding the rings in one place. i believe those rings are supposed to be able to slide around the piston. i usually just set the ends of the two rings apart from each other and call it a day and install it, never had a problem. i havent pulled the piston on the chinee yet, but i dont know of any pin holding the rings from spinning. hey, wheres norm at......or anyone thats done a teardown, anybody?
