Title says it, how do you do it. I have looked all over the internet, and seem to be missing something obvious.

use the 1/4 " screw on the throttle linkage, it has a flat head screwdriver head on it.

 

Sometimes the Performer/Carter carbs are hard to get to stabilise, idle-wise. Don't know why but a 1406 that I had always jumped around 100 rpms or so now matter what we did.

Went back to my QJet and problem solved.
