Thanks for the info. Do they make custom ring sets or modify some "close" rings? Got a couple small engines that need special rings as the pistons and the bore looks pretty good.
A few years back I was overhauling a small block Chevy V-8 bored 1/16 over and found out it took the same rings as a '53 DeSoto without having to grind the ends. Just pure luck.
Google "Otto gas engine works" They make rings from 5/8" diameter to 56" That should cover most things!!
