Larry for a simple trouble shoot, hot wire from the battery or a hot accesory wire directly to the coil and see if that will start it.

To The Red. Thanks for your reply. Have 12.4 V to the coil and 12.4 from the negative side of the coil to the isolator stud that passes thru the distributor. Also have 12.4 V to the point tip. No spark from the points. So, which side of the coil, positive or negative would I run the hot wire to?

Sounds like that is not the problem. Are the points closing all the way?

Yes they are. Juice to the distributor but it doesn't come out of the distributor.

Do you have voltage on the post where the points spring arm attaches? It should be only around 7 volts.

Put your voltmeter from the hot side of the points to a good ground (not on the distributer itself). Pull the coil wire to the center of the distributer off so it can't start. Crank the motor, by hand if you can, if not use the starter. Watch the voltmeter. It should alternatly show 12.4 volts and then zero volts (or close to it). If the volts remain steady, the problem is in the points, if the volts go up and down, the points work and we should look somewhere else.
