dan williams Posted January 18, 2010 Report Share Posted January 18, 2010 No problem getting a thermoswitch. I think they've used the same one for 15 years. You'll have to call dealer for price. I suggest you get a MotionPro ratcheting spark plug wrench. Nice and thin and easy to get into the tiny space over the plug. Sounds like you still have a blocked pilot jet. You really must disassemble the whole carb and blow out all the passageways as well as the jets. If you do it with the carb assembled you just blow dirt in deeper. Carb cleaner is OK but make sure it's dry before assembly. In other words use the carb cleaner THEN blow out the carb with compressed air. Also look up the Billy Traynor carb setup article in these forums for how to set the floats on the Mikuni and how to keep it from piddling fuel all over the place.
