Checked all the searches and not finding what I'm looking for. Has anyone here played with the air screw adjustment that is behind the intake bell? And if so what kind of results did you obtain? Thanks in advance.

good luck finding help. i couldn't find much help. the adjustable skrew is an air skrew. the other jet is a main air jet. i haven't talked to many people who have messed with either. the air skrew and fuel skrew are both for very low throttle positions. if your not getting a miss off idle, i wouldn't mess with it. if you are, i would first get an adjustable fuel skrew and play with that and your pilot jet. if that doens't fix it, i would then play with the air skrew and possibly even the needle. i think i left the air skrew between 2 and 2.5 turns out.
