Adjusting carburetor?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I put a new Quadrajet ( 4 barrel ) on my truck, I did this about 6 months ago, well, all I have done was took it right out the box and installed it. Well, I would like to try and get a little better milliage out of the engine, it is running rich, I am not sure what all I can try to adjust on the carb. And which way to move the adjustments, I know where the air fuel adjustment is at, just not sure which way to move them. The engine is a stock 305 out of an 86 chevy truck. It is a big time dog, I just installed a 700r4 in the truck, and just looking to try and pinch a litle more fuel milage out of it. Some one help me out here.
