Re: carb replacement for 1986 rude 140hp
After cleaning carbs an throttle bodies, I noticed that the carbs have adjustable idle air screws at the top left of carbs. the idle and midrange jets have the same jet size # 33's, I have boysen reeds in the 140 which require richer idle, should I change the a 33 down to a 29 or 28 or will the idle adjustment screw do the same thing. Thanks for any input.
