Thank you guys. Yes, I"m running a temporary gas can above the carburetor, and it is secure enough. I'm not driving it. I will get the actual tank in service before it moves. And for this reason, the fuel pump is not an issue. I believe i'm dealing with something going on in the carb. 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? Seems excessive. Lastly, this is a different carb, doing the same thing. It is possible both are dirty, or have the same problem, but I rebuilt the first one recently, and the one on there now was rebuilt 15 years ago, parked, got dirty, and I cleaned it out and thought I'd give it a try. Stumped.
