gvictor4,
If the rig starts and has lots of fuel up to the carburetor, it sure sounds like it is the carburetor itself.
Just for grins, rap on the side of the carburetor with a screwdriver handle. You might wake up a stuck float.
If you can do it VERY carefully, try and keep the truck running by pouring little amounts of fuel down the carburetor after you get it started.
This will tell you every other system is working except the fuel system. Be very careful with the gas ...a backfire could cause havoc.
Pay no attention to the Johnson rod remark, it was said in jest.
Good luck and keep a wet towel handy for fires!
