Carb problems???

[66Dog&Pony]

I am working on restoring a 70 base coupe, 302, 2 barrel carb. Car has been sitting for about 2 years prior to my buying. All is going fair other than that it is running very rich. Carb is Motorcraft 2100D. It seems that auto choke is sticking. I have disassembled, cleaned, lubricated and all looks well but car still runs rich. Suggestions? How do you adjust air/fuel settings on this particular carb?
Thanks all!

adjusters are at the front bottom of carb . two screws left side and right side
the average turn is all the way in and 1 1/2 - 2 turns out but that may vary
