Does it stay running with the choke on? Then it is a fuel problem OR a vacuum leak(manifold to carb or block). Compression check. See valve adjustment.
Valve adjustment. May have sticking valves. Timing.
All part of the fun of reviving our history.

I'd say timing, either mag is set wrong plug wires are wrong or you could as I once had have a worn coupling b/w mag and drive. It drove me nuts trying to find that one, I'd set the timing and it would run fine then start backfiring and popping. Thinking i had set timing wrong I'd reset and same thing. Changed the mag drive assembly and no problems since.

Is it a mag or a distributor machine? I ask this because if it's a mag, and you put new pugs and wires on, you can make the mistake of not realizing that the mags are counter cyclical. If you put the wires on assuming the rotation is the same as the driver of the mag you will be 180 degrees off. Cylinders 1&4 will fire but 3&2 won't. Try switching # 3 & 2 wires and see if it runs. LOL!

Sounds like you have rust impeding gas flow. Check the sediment bowl, fuel line, screen in gas tank, and bowl in carb.
