Finally discovered after hours and hours of process of elimination, I’ve figured out that fuel was arriving to the carburetor via either fuel pump, but wasn’t filling the bowl. Because of this the truck would stall and die simply because it ran out of fuel as I originally suspected. But to eliminate any doubt along the way if you saw the last 2 videos I did a lot of testing. Finally determined it was the needle and seat locking up and blocking fuel from filling the bowl. Turns out the Holley 2 barrel is very touchy where the fuel line connects, because that brass fitting the line goes into is also the needle and seat and just but cracking it back a hair and tapping he carb with a brass hammer.. it was released and ran again!
