Vacuum leaks are a great place to start, if you are comfortable messing with the carb the air fuel mixture.
Take a can of starting fluid start the truck and spray each vacuum hose at a time or base of carb, but start with small areas. The truck while running should stumble if there is a vacuum leak with the starting fluid. Be careful starting fluid is flammable so spray with face as far away as possible and not on exhaust.

while not running pull the top of the air filter off and pump the throttle linkage a few times while looking down in the carb. If you don't see any gas come out of the little tubes shooter then time to check your fuel filter if your getting gas through it. Check the flow from the tank it may have some crap plugging it. If you remove gas line at carb and gas pumps out good while cranking motor with coil wire removed.try to catch the gas ez for a fire so be careful. Then time to rebuild the carb. But if that scares you. You may get away with just replacing the accelerator pump and the. If it has a 70's carb it will have a little red rubber check valve inside the accelerator diaphragm. But you'll have to remove the top part of the carb to get to the float bowl then remove the float to pull the new rubber check valve through. MY 2cents

At this point, after verifying that it is getting all the gas it needs, I would be buying a rebuild kit. Not much to this, just keep your parts in order, and do it all at one time. A can of carb cleaner would be useful too. My neighbor wants help putting a new carb on his 460. So he orders it, and a 1 bbl shows up. WTF?, the parts guy didnt notice this?
