I let life get in the way of riding for to long and let some gas get nasty in the carb. I cleaned the diaphragm, got some fresh fuel and got it going fairly easily. However, now it won't stay running without the enricher open and the throttle doesn't respond right away. All the likely causes based on the carb troubleshooting section in the manual point to jetting and/or needle and seat problems. My question is, should I just plan on rebuilding the carb to correct those problems? It's a CV40 and I'm fairly :think confident I could do it will Dave's tutorial, but idk if that's completely necessary or not. Any advice would be greatly appreciated.
