John Deere pony motor coil transplant update-
I finished up installing the pony motor coil on
the 72A Eismann magneto for the OB35A Neptune 4 hp.
It appears to be a success. I didn’t have to butcher
up the mag plate as much as I feared, and had
not using the big rat tail file been so much fun,
I could have enlarged the hole less, and made
a better fit for my over sized grommets.
For now, I reused the Wico style condenser with
the threaded end for the primary coil, kill wire,
and points connections. It tested at .32 mfd’s.
Anyone know what the John Deere Pony Coil
condensers are rated at?
Moral of the story, if you try the B&S coil conversion, I hope you
have better luck then me. I’ll be using the pony motor coils
instead. Besides, they’re much easier to find and relatively
affordable.
Tried uploading a video 3 times to YouTube, but it never finishes processing,
and the narrative is nothing but static, so you might want to turn your
sound off!
It does “spark” okay pulling it over by hand, but that’s problematic
doing while filming, unless you have three hands, hence the electric drill, lol.
Prepare to be boarded!
