Ignition or Fuel?

If you have a different carb, throw it on and see what happens.

Demon Sizzle knows what he is doing!..........But hay sh*t happens.

Also try a different coil. Even the stock one, if you still have it.

Look at the fire wall loom and see if there is any wires going through there that look like they have been hot(insulation blackened or melted).

If so wiggle that wire and the same wire under the dash. If it fixes you problem, you have some work ahead of ya...............
