I have a mercruiser I.O. 305 chevy 4 barrell I had the carb rebuilt and seems to be running very good and smothe at idle and when I gas it.I was told how to adjust the air mix screw .It does not seem to make much differance if I go in all the way or out all the way I cannot tell the differance. I have put it 2 full turns out and seems to be running good . What do you guys think of this thanks
