Mike,
What coil are you using (you may or may not need a ballast resistor, depending on its resistance)?
Are you using a ballast resistor?
Things to check or replace, in order of difficulty and cost:
Timing adjustment
Valve lash adjustment
Carburetor adjustment
Check/replace fuel filter
Ignition/plug wires (if you do not need them, you now have spares)
Rotor (if you do not need it, you now have a spare)
Distributor cap (if you do not need it, you now have a spare)
Run a ground wire from a screw on the distributor to head
Rebuild/replace carburetor
