    I hope I don’t insult anyone, but here are some basic things to check:

    1. The cam is installed correctly ("top" appears on top) and the cam is the correct one. Sometimes you can tell if a motor has been butchered up, and parts swapped between models. It’s not always obvious, but if you find something wonky on one part of the motor, suspect anything else that could have been messed up.

    2. The flywheel is original to the motor. I think they used both WICO and Phelon systems post 1958.

    3. The coil primary wire is hooked up to the correct set of points. With one set of points open, verify that when you install the flywheel, that the magnets are passing the coil hooked up to the open points.

    4. The points are working. Disconnect the coil and the condenser from the points. Measure continuity across the points by connecting to the insulated point contact and the mag plate. Verify no continuity with the points open, and less that a few tenths of a ohm with the points closed.

    Can you post a photo of the mag, or send it to me? I can compare it to my motor to see whether it’s the same (I have a 12 hp version, basically the same as far as I know) and to check to see whether I have an extra mag.
