i agree Gary, i have never heard of a mechanical pump putting out too much pressure, ever, but i want to test it, so i can eliminate that from the list of "might be's"
Process of elimination is the best on these sort of issues.
Tell me, people who tend to understand the joys and frustrations of owning an older truck, would it be wise of me to possibly look around for a second carb, identical to this one, and have it rebuilt as well, to have a back up to very easily swap on during moments like these? I'm getting quite good at pulling this carb, as removal or installation can take no more than 2 minutes anymore. I'm even to the point of keeping the proper tools in the underhood toolbox.

Glad you/he found the problem. It had to be something simple like that. And, now that you've checked so many other things in this quest I'm sure you will have clear sailing - at least as far as the fuel system goes.
But, regarding the question about having another carb "in the wings", I don't see the need. I don't have one and haven't needed one. The Carter 1bbl is a very reliable carb, with none of the normal things that go wrong in everyday use in its design. (In my ~50 years of carb work I've never had a float go bad in service.) So, if you feed it clean fuel and air it should serve you for many years w/o problems.
Wouldn't hurt to have one as a spare. But the float was bad from the factory. Although it didn't fail immediately it obviously had a flaw that turned up very quickly. That is very unusual - at least in my experience.
Glad you found your issue . Although excess pressure is rare , I have seen it a few times .Floats , seen a lot bad . I would not bother keeping a rebuilt on hand , but , a second carb on hand would be nice . I would learn how to build it myself , If I were you .Keep a kit on hand , good to go in a short time ! Simple carbs , easy to build , reliable .
