Well, it really depends upon why it's running too rich. It could be a weak O2 sensor, improperly adjusted carb, float set improperly or fuel-soaked float, leaking well plugs, mixture control solenoid inoperative, etc., etc., etc.
Is your SES light coming on? If so, have you checked the trouble code(s) being set?

Well, you may have eliminated one possibility. I should also have added improper timing/ignition.
