Re: 1940 Johnson HD-15 Magneto testing

[Buccaneer]

I put the magneto and flywheel back on the HD-15.
Hooked up a timing light and spun the engine over
with a drill, with the top plug wire hooked up first.
Nice steady indication near my TDC mark, with
no wild flashes that I could detect. Switched to the
bottom plug wire, and same results.
Threw the outboard in the test barrel and
finally got it to stay running by tweaking
the High and Low needles. Unfortunately,
it’s singing the same crappy, irratic tune.
Think I’m done with this one for now so
I can concentrate on other things,
but thanks for all the help Joe!

Prepare to be boarded!
