well after having my carb rebuilt twice it still didn't do right it would run ok when picked it up and progressively get worse over 30-45 days until would no longer start and if it does it runs really lean,(all my fault I left the gas in it that winter). So I gave up on the bike shop rebuilding it and we tried it, we got it clean but we took the adapter off the bottom of the carb and now find out gaskets are not available at least the ones I need. ANy suggestions, what carb can I use anyone got a used one, etc. Yamaha wants 2200.00 for a new one, not happening, found a replacement for 620.00 can't afford. any ideas guys.
