Advice on adjusting the idle 1966 vip with a 400 in it

[rsh1966vip]

Do I turn the screw counter clock wise to reduce my idle RPMs?

thanks

The large screw you have circled is for your fast idle choke speed. The smaller screw above is for your curb idle warm engine speed.
First get engine up to operating temp, then I start with correct what the engine wants timing. After that I will set my idle speed. Then when engine cold and started you can adjust the fast idle screw.
Where is your throttle cable and kick down linkage?

Follow what Boydsdodge said. Clockwise to raise idle. on both screws.

I also see an open vacuum port on the front of carb.

Thermoquad!
Best to search for a 70's style kickdown linkage from carb to trans lever.
Or get a Lokar kickdown cable assembly. I had good luck with those, and easy to install and adjust.

Can you post a photo of your carb? Left and right side angles.
