No spark, have changed everything, what's nest?

Asked by Bill Jun 20, 2020 at 03:36 PM about the Chevrolet 3100

Question type: Maintenance & Repair

Last summer I had my 1950 3100 thoroughly tuned up and ready to go. It was
running great. This spring I cannot seem to get a spark out of her. I have
replaced the battery, coil, points, condenser, and rotor, nothing. What am I
missing?

Do you have power to the coil and distributor? How about the spark plug wires and coil wire? If you have coil resistor make sure it is working. Use a multi meter to test for power.

So it turned out to be simple. I had replaced the Rotor and the condenser because there was evidence of arcing in the rotor. Somehow, the points were moved, didn't even think to check since I hadn't (intentionally) touched them. Set the points and she's running like a top.
