Out or down for more fuel, in or up for less. Out to quell popping on deceleration. If it was me, though, I'd be checking the vacuum caps for dry rot since you've got that cough going on.

Excusssse meeeeeee for stating air screw instead of Idle Mixture Screw!!!! Been racing and riding bikes over forty years, and used the vernacular flat tracker version instead of 'formal'.

No worries, all is forgiven...FWIW, I also razz 2T tuners that refer to it as a "fuel" screw... At least you didn't call it a "dinglehopper"

The pilot fuel screw only controls 1 of 5 pilot holes; the 4 other pilot jet bypass holes are under the throttle plate (when closed) & are not controlled by the screw.

You put yourself at risk at more than 4 turns out.
