Oiwa Garage Tech Note

"This is the inner carburetor mount O-ring. A hunting idle that changes when you spray carb cleaner near the base is a leaking mount seal. Fit a fresh O-ring and torque the carb evenly."

Frequently Asked Questions

How do I check the carburetor mount seal?

With the engine idling, spray a little carb cleaner around the carb base; if the idle changes, unmetered air is leaking past a hard mount O-ring - replace it.

Should I torque the carburetor evenly?

Yes. Fit the fresh O-ring and torque the carb base evenly so it seals without warping the flange and creating a fresh air leak.
