Still Not Running Right

once you get it started, try just bumping the accelerator pump to see if that keeps it running (based on your video, i wonder if that's effectively what you are doing to keep it going). if it does it might tell you it's wanting fuel for some reason.

was the carb rebuilt to stock specs for your engine? is your engine stock? what's your timing doing at idle and low RPMs?
 
was the carb rebuilt to stock specs for your engine? As far as I know yes,

is your engine stock? Not too far from stock, cannot give a good answer as the engine builder never gave me a build sheet. I have no idea what is in there.

what's your timing doing at idle and low RPMs? Cannot keep the car running at low rpms to check this. If the RPMs get below 1100 the car dies.
 
did you try bumping the accelerator pump? I am sorry, I am not sure what you mean by bumping the pump.

what is the timing doing at 1100 and up? I have not checked the timing recently as I had not been able to keep the car running without pumping the accelerator.
 
from one of your videos it almost sounded as if you would be able to get a ballpark estimate of what your timing is between throttle hits.

the accelerator pump is an arm connected to the throttle that squirts fuel. look at your carb and you should see the pump (or google holley and accelerator pump and you should find a diagram).

just trying to help and narrow down what the issue may be.
