Still won't start

[Tom Wesenberg]

Battery positive ground, the black coil wire should have 6 volts at all times and go to the coil - primary post. The red wire should go from the coil + post to the switch, then down to the points. In late 1929 the coil terminals changed sides for polarity. Don't worry about the coil polarity for now, because it will run either way.

Do you get any sparks from the coil wire to the head nut? If not, stop the engine with the points open and key ON, then short the points contacts with a screwdriver, off and on, and see if you get a spark out of the coil wire.

Once you get sparks from the coil wire, then check the rotor and cap. I've seen a couple rotors that shorted the high voltage through the plastic to the distributor cam, so it never reached the tip of the rotor.
