    Yes, the primary circuits are hooked up in series, and I had never
    seen such a system either.

    Coils were tested several ways, many times, and always passed with flying colors.
    Yesterday I switched out the .23 mfd aftermarket condenser with a .15 electronic
    capacitor, reinstalled the magnet, and reinstalled a non original ground wire
    between the magneto, and powerhead, which I had previously tried.
    Reset the points again, and it appeared to have good spark on both old, shorty plugs.

    I dug out some new NGK plugs and tried them out for kicks, after squirting some
    gas in the carb. There may be a Christmas Miracle in the works!

    It looks like the rotating magnet is “off the hook”.
