I have had this truck for about 6 months. I bought it for $350 and put a rebuilt engine in it, new carb, new plugs, wires, o2sensor, fuel pump, fuel filter, and have serviced the 5 speed Standard transmission and rear end. And I cannot adjust the fuel/air mixture on the carb to make it stop smoking (black smoke). No matter how much I adjust the screw it continues to smoke. What are some other reasons it could be smoking like this? I should also mention this was a carb bought from auto zone, not the weber I see so many ppl going to.

Is the carb a replica, or a rebuilt OEM carb? Do you have a pics of the carb setup?

It is a rebuilt OEM carb. I'll take some pictures today and post them.
