86 C10 4.3 Dead spot when accelerating

[tablerock4]

When starting off, the truck will stall if I don't give if alot of gas or give it a pump as I initially accelerate. This problem is minor when the engine is cold and gets increasingly worse as the engine warms up. It's that one spot when I just start to push the accelerator pedal. It's almost like a hick-up at the very beginning of acceleration. At operating temp, I can't just lightly touch the pedal to slowly creep forward, like you would in traffic, it will stall. I have tried the following:

New Carb
New Distributer Cap & Rotor
New Ignition Wires
Advanced the timing
Increased idle speed
Checked for vacuum leaks
Cooler thermostat (helped a little)

I am really stumped. Any advice is very welcome!!

Thanks
