I know it's a long shot, but I can't seem to find any leads. I heard once that some motorcycle rings would interchange. Do yall know of anything that could swap in. I'm ordering and overhaul gasket set and carb rebuild kit. Im planing on going through the whole engine this winter and installing a starter/generator to make it a little more user friendly. I want to get it ready for parades this summer. Any help would be appreciated.
