I have a brand new rebuilt carb that I ordered online, but I guess I really have no idea how it is adjusted. Like I mentioned, the idle screws are about 3 turns out, but that should have very little to do with the mileage driving back and forth to work on the interstate, right?
Is there some way to adjust the other jets in this carb? Or, is there something else causing the rich condition? It's a stock Quadrajet E4ME.

Forgot to mention:
Stock 350
4 bbl carb
31" tires
700R4 and I use the overdrive on the highway
3.42 gears
Shouldn't I be getting at least 12-14mpg? Heck, the specs for that year say 15.
