The search button is your friend.

The adjustment that needs to be made is under the black plastic cover on the top of the AFM, and you're not merely turning a screw. Pry that cover off and you'll see a clockspring attached to a toothed wheel. You need to move the position of the spring relative to the wheel. Specifically you want to tighten the spring, so that the flapper deflects by a smaller amount for a given airflow.

if it were me and it's a oem AFM, id simple drill out the idle-screw cap, and turn that back about one full turn counter-clockwise.
