BCA, I doubt it is the timing. Dwell is more important
Without being there it's not easy. Can you bypass your fuel suction line by running an alternative line to the pump?(incase you have an air leak)
Can you run a test on the fuel pump? Run a hose from the pump delivery to a tin, to see what volumn the pump delivers (the motor should run a bit on a carb full) I dont have specs, but should be a reasonable amount.
Does the accelerator pump work (carb) can you see it squirt the fuel down the carb?
The old coils and condensers are notorious for failing insulation. That includes NOS. In both cases, they deteriorate in storage.
I'd try a new (not nos) condenser. Anything you can hook up will do to try it for temporary.
I'd also try a direct feed to the coil (bypass the ignition switch and ignition resistor (not for too long)
It hasn't got a blocked exhaust has it?
See how you go.
