    Wow, great!
    I remember looking in the flywheel hole some time back the coils were black and looked in good shape. I suppose I may have a 1951 ignition? I know they didn’t look all cracked like the layer coils would do
    Today, I’ll be at the lake where the motor is, and I plan to get at the magneto and get some answers
    I’m bringing my coil tester !
    Thanks for everything, everybody!

    Success !!
    Frank, your suggestion the motor was on only one cylinder was correct!- the lower had no spark
    I tore into everything at the lake yesterday, and found I have the early 1951 style coils which looked amazing, and the Stevens tester confirmed they put out a hefty spark at 1.2 amps
    I cleaned the points and installed some .75 cent capacitors (.22uf) from Digi-Key in the place of the old condensers
    As simple as that was, I was previously in denial the ignition could be at fault.
    May this be the last time I don’t scrutinize the ignition first!
    Now the motor runs at full, planes the boat with two people……
    And I learned a bit more about 2-stroke carburetors!
    Thanks to everyone on here who has been so generous with their information, experience and time.

    just tuck the long wires away from any moving parts
