Spoke too soon. :( Still the occasional pop/cough from the carb and it dieseled on me twice today.
Any advice? I'm going to try and re-tune the carb based on the factory directions. If that doesn't do anything, I guess I'll have to tear it apart and check the jets.
Do you think there would be a need for a jet change going from the gutted stock pipe to the normal stock pipe?
