It is dripping gas out the bottom of the carb (remember it is an updraft) and I actually saw it squirt out once during cranking. I don't understand this. I can imagine flooding, but what would pull the gas out of the throat of the carb. There is a governor also on this truck right above the carb, before the manifold, and it is getting moist. Can the intake suction pull gas out of the carb and up into the manifold in the form of a liquid?
Do you have the air cleaner on and is it clean? A dirty air cleaner can act like a choke and get liquid gas into the manifold. The gas sprays out in small droplets and takes a bit of time to evaporate. When you saw a squirt, was that when the accelerator pump was activated? That would indicate leakage from a carb gasket.
