I will try a few more things and then throw in the towel. It is foolishness to keep spending $25 a whack to try air bleeds or jets. I can only think of one other thing to try anyway - go up in the IAB size.
Idle was mostly set without touching curb idle screw. I went up about 1/4 turn. I am sure the transition slots are still good. The four idle mixture screws are out about 1.5 turns.

My carb did much the same as yours until I removed the idle feed restrictors completely. Try it and see. You'll need a tiny allen wrench to remove all four from the metering blocks.
