Hello, timbermn20, and WELCOME to KZR!
We're glad you're here!
Am just guessing without a manual, but would start with pilot air screw 1 1/2 turns out from lightly seated.
Then coordinate throttle screw and air screw adjustments until achieving the best steady idle at the lowest slide position.
Typical procedure is to turn air screw slightly back and forth to highest idle. Then lower slide with throttle screw to almost stall. Then readjust air screw for possibly higher idle.
And keep repeating this until further adjustment of the air screw either way only worsens the idle. At this position, the air screw adjustment is as good as it's going to get.
Lastly, set throttle screw for desired idle rpm.
More importantly, if not already done, before addressing the carbs at all, should first assure correct valve clearances, install brand new spark plug, assure correct fuel level in floatbowl, and install a new in-line fuel filter.
Because even a perfect carb can't compensate for shortcomings in the other components.
Good Luck!
For reference if needed.

Pattons advice is true, and his start point exactly right from my antiquated service spec book. luck G, and welcome.
