I never got and sage advice on my last query regarding this
coil swap, so thought I’d just forge ahead, and “wing it”.

The original K coil lamination would almost fit  an OMC coil
with little effort, but, there’s no good way to orient the coil
where there wouldn’t be clearance issues with the flywheel,
or other.

I have a couple of Tecumseh small engine coils I purchased
in the past for a possibility on a different magneto coil swap,
which didn’t work out, but “maybe” will on this one.

In this orientation, the flywheel hub would likely rub.

This orientation looks “doable”.  I checked the height,
and it looks like there would be enough clearance so
that the flywheel would not rub.
I started machining down the width of the lamination
to fit, but I still have to remove some laminations
on the height so the coil will slide on.

The only “issue” that may dampen my hopes and dreams,
is that the plug wire on this Tecumseh coil is too short,
and it seems to be “glued in” place. Hopefully the
coil is still useable after I get the plug wire out.

Plan “C”, would be a Military surplus Bendix Scintilla
coil, which would fit fine, but I dread removing those
coil laminates.
