I used the truck last night. Pumped the gas 4 or 5 times and it fired right up. Now I don't know what to think. i didn't ave time or light to check the level in the bowl. Guess I should let it sit for a week+ and see how it is.

If you let a carbureted vehicle sit for a couple of days, normal starting procedure should be as follows:
1. - Turn key to "start."
2. - Press accelerator pedal all the way to the floor (to set the choke).
3. - Pump accelerator pedal once or twice and release.
3. - Crank engine.
If you let it sit for a week or more, what happens is the fuel has started to evaporate out of the carburetor's fuel bowl(s). When this happens, your starting procedure is going to be a little bit different:
1. - Turn key to "start."
2. - DO NOT PUMP THE GAS YET. Crank engine for about 10 seconds. This will energize the fuel pump and get gas back to the fuel bowl.
3. - Press accelerator pedal all the way to the floor (to set the choke).
4. - Pump accelerator pedal three or four times and release.
4. - Crank engine.
If your engine still fails to start, you have another problem somewhere. If the accelerator pump diaphragm checks out ok, check your fuel pump for leaks.

Ok, I used the truck this weekend, and followed procedure #2 above. Cranked for about 10 seconds, set choke, pumped gas 3-4 times, and it fired immediately and died. Pumped 2-3 more times and it started up fine. This is acceptable to me, but is it normal?

Yes, that sounds normal. 
The next time you have to use procedure #2, after you crank the engine over for 10 seconds, try pumping the pedal 5 - 7 times and then see if it starts up. Any more than that and you will probably flood the engine, so don't!
