My step son took my truck for an apparent joy ride while drunk, ran it cout of gas, even in carburator, put new fuel in and now it is bogged down, wont stay running, and lots of black smoke pouring out...
Sounds like a flooded carburetor. Possibly float needle dropped since bowl was not full enough to keep float needle in place. This could be from improper adjustment during carburetor overhaul. When floats are set, some have adjustments for both top cutoff and bottom drop.
Now if black smoke is not from exhaust pipes, you have a bigger problem. Could new fuel be contaminated with diesel? Also depending on carburetor type, the rear barrels of a 4 barrel carb can soot up if the rear barrels are not often open. Some rear barrel actuators are vacuum operated, others are mechanical links.
Some other thoughts are metering rods can be extended and jam if either the seat unscrews or the rod hangs up. Not common, but possible. Free floating rust could jam the metering rod in almost any position. When placing a carburetor on the intake manifold, NEVER turn the carburetor upside down or at any angle that the truck would not normally go. The float pin can slide out of some models.
Also, was the gas used from a 2 cycle engine like a boat or lawnmower that has oil in the gas?
