I am trying to get a carb tuned in on an hp500. The carb was freshened up and had #70 jets in the primary. The secondary numbers I cant make out. The motor is running very rich. Float level is correct, the air bleed vaves are free of debris, there is about .001 inch clearence on the primary accellerator pump rod. Are these jets too big? If so what should I start with. Thanks in advance for your input.
