If your using the exhaust system from Ryca, and a pod filter directly on the carb, that may be the problem, rather than the stock carb, and changing carbs might not help .
The thing ran rich for a while. Then he did the RYCA carb mods. It ran okay after that, but still seemed rich. It sits for many weeks at a time. Now it is hard to start, and just doesn't run very well. The carb has been apart a few times.
RYCA air filter mounted directly on the carb. RYCA exhaust. Otherwise the motor is stock. We did the cam chain tensioner mod a thousand miles ago.
I don't necessarily want him to change the carb, but he is fed up and is of the mindset that if this carb is dumped, the mystery problems will go away when starting from scratch.
