Yur timing is IMO lying to you. Crank in the ignition timing and close the speed screw until the throttle blades get back down on the bottom of the transfer slots, and the mixture screws start working again. Then check the manifold vacuum . If it ain't over ~16 inches at 650(N/P), then check the cam timing.
If it is over 16, then prove the index TDC is true TDC #1 cylinder on compression stroke.

well, at least the power-piston is staying down. You know, with your cover,you can raise the needles manually, and see if the engine responds favorably.
I still hear what I think is a huge vacuum leak. If true, then raising the needles manually will both speed the engine up AND smooth it out.
On the list I made earlier,post 52, I forgot to include wrong base gasket, in the sources for air leaks, I will go edit it right now. Ok, no; it's there.
For that 2-bbl there are a couple of different base gaskets available
