For an engine to run, you need :
1) Spark at the right time.
2) air/fuel mixture. (You have fuel, but is there water in it, or crud buildup on the inside of the tank? 10% ethanol gas is a "wonderful" solvent for dissolving crud which then migrates down stream to clog the tiny holes in the block of aluminum which is your carburetor.)
3) Compression. (You say that you have never driven this truck. How long has the engine been sitting? The crud mentioned above, can also cause the valves to stick resulting in bent valves which will prevent compression.)
BTW, you need to save your "high level of frustration" for more significant problems, like starting a newly rebuilt engine, having neglected to torque down the connecting rods...
