If you have good pts, coil and condenser, three things I would also check out:

1-Pull all of the plugs and keep the wires attached to them. Lay the plugs on top of the engine. Have someone crank the engine. A good bright spark at the end of the plug indicates good wires and correctly functioning spark plugs. reinsert the plugs and move on to #2...

2-close the fuel value to the fuel pump and then remove the bottom brass plug under the fuel jet of the carb (closer to the radiator) and then the square headed jet hidden inside the plug cavity(you may need a 16 point socket). Make sure to capture the gas as it will come out of the fuel bowl and jet well. Once you have the jet removed ensure that there is no obstruction or small particle stuck to the wall or the jet orifice...

3-completely drain the fuel vacuum pump, then close the fuel valve to the carb and put new gas in the pump by filling the top of the fuel pump. Ensure that the brass fuel filter screen does not have any particles on it and make sure there is NOT another modern fuel filter somewhere between the gas tank and the gas pump (mine was tucked neatly inside the frames channel beam). Open the fuel value briefly to have it flush out your fuel bowl and then reinstall the jet and make sure you install a new crush-able copper washer on the brass plug.

Best of luck
