My first guess would be ignition timing, then cam timing. Verify both. Let us know when you find the issue.

I'd bet on ignition timing also. Having the distributor locked at a certain figure (34/36 in this case) is NOT the same as initial timing. Think of this for a minute, I would doubt you could even get it started if you had 34 degrees initial timing.

Buying one complete have the seller put it on stand and and check as much as possible or if they don’t want to do that start deducting or walk away, it could cost you in the long run. Doug

Could the stock timing cover marks be off with the ATI damper?

The reason for the compression test was to perhaps shed some light on the cam timing situation.
If it was way low you’d have reason to suspect the cam was retarded.

Make sure the distributor pickup coil is not wired backwards.

Alright so figure out if the vacuum leak is between the carb and intake, intake and heads, or someplace else. Try carb clean/starting fluid trick
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

Definitely try carb cleaner or something near the intake to head area, underside by the valley pan, and around the base of the carb.
Like others have mentioned, it’s either too lean or the timing is retarded. You’ve verified the timing mark with a piston stop so that is likely ruled out, but if it doesn’t die with your hand covering the carb it sounds like it’s getting excess air somewhere.
