Remove plate on top of flywheel allows you to inspect coils.----Or remove the flywheel.------Inspect magneto.-----Coils may be old and cracked.----Or breaker points may need cleaning and adjusted to 0.020"

I did the points, coils look good, the magneto look like it’s been ground down is that normal?

There should be no need to do any grinding on these parts.-----If coils look good and you did the points then there should be spark.----Often I see folks confused when working on this simple magneto.

The motor is a 1959 model.----A complete evaluation should be done before spending money on parts.
