you first install the carb on your engine and run engine to 50km then check your spark plug : if light your jetting is small if dark your jetting is high and if light with brown your jetting is correct .
before mounting carb in your engine do not change any things .
Certainly for tuning and testing the carb use vacuum geage not your ears !!!
