Default Re: No spark

Just want to be sure wiring is correct and that you have voltage on the coil pos terminal when the motor is cranking. There may be a glitch that interrupts the voltage when key is turned to start.
Just put a test light on the coil pos and have someone crank motor with the ignition switch and see that the light stays lit. If it does, that's good, if it goes out, that's bad. Report that ASAP.


Point gap: Take off distributor cap. Bump starter or push truck so that the rub block on the points is on a one of the high "lobes" of the distributor shaft. In other words resting on a high ridge. Leave it right there. This will open the points to max open. Use a feeler gauge to see what the gap is now. You want .016-.019. You will barley loosen the screw on the points slot and use the built in screw driver pry tabs to move the points to get the gap...or however you can get the point assembly to move.
The gap will try to move when you re torque that screw. Watch out for that!!! Recheck the gap after screw is tight. You may have to play with that some but it's REAL important.
Also make sure your distributor plug wires are in the proper firing order. Search the internet and read all you can find on setting points and general old time auto ignition systems. Don't think you have a big problem. One step at a time will find it. Post what you find out. We all need to know the results of each step.

You did not answer this: Was it Running into the garage, then you did AC and points? then no start?
You didn't leave the distributor rotor off did you? When you put points/condenser on?
