I've been having trouble with my JD 260 (Kaw FC540V). It'll fire up on ether and then die right away I put a new fuel filter and spark plug on and that didn't help. I verified that I'm getting gas to the carb. I also took the bowl off and sprayed in there and sprayed in the throttle body. I know that this isn't the way to clean carbs, but just wanted to see if it would make a difference.
