Im having such bad luck with this carb setup I'm ready to sell the truck for a dollar.
So I removed the carb tops to punch the holes in the gasket because the holes were already done in the top cab half already. Inspection it closely i noticed the gasket holes are probably unnecessary. The gasket is actually open around the float pivot pine any ways to allow for the pressure to be the same on both sides of the gasket. I also noticed there is also a stock pin hole vent port that goes from the top cap into the top of the venturi. Not sure why tom says the holes are mandatory possibly the stock one is just too small?
So i went out with the truck for a test drive with both cabs reconnected. Drove like it did before. All groggy, smelling like gas again, no acceleration. All of a sudden she just went all boggy. Like no fuel was being pumped in or delivered. then all of a sudden it working again and then not working. Opened the hood to see that one of the accelerator pump arms is actually stuck in the open position.

Truck fired fine after that and i managed to turn the truck around and start driving back home. Then like sure as [censored] when i started to press the pedal the truck would just die 100% and stall.
Opened the hood. pump arm was ok...................disconnected the carbs so they were independent of each other to see if one was causing an issue and guess what! the other carb that was running the truck by fine by itself (carb "B") about a week ago would kill the engine every time you you try to open the throttle slightest bit. If you just push on the carb throttle 1/16" the motor would die. Re attached the other carb that was not working correct as diagnosed last week (carb A) and managed to just roll her home in 1st gear.
Yesterday i gave up and ordered 2 more carbs from tom. I have no idea what it can be or what i have done. I bought the carbs last year, i installed them via the 4 bolts on the bottom i hooked up a fuel line after flushing it and installing a filter and im having this issue. Thinking a V8 is in order as much as im not wanting to go that route.
