I recommend going to a solid state module as well but I disagree
with the price. They run between $35 and $45 depending.

I saw those, but I was curious on a retrofit, how does the module detect the
rotationial position? Do you have to drill in and install a magnet or
something?

The same flywheel magnets are used for both. The coil just senses
when the flywheel magnet passes. No modification needed. Just bolt in
place of the old coil.

One side note here is that while on a points ignition if the
flywheel key is sheared then you loose spark. On the other hand with
the solid state ignition it doesn't matter and it will spark even if
it's 180 deg out. This can be confusing sometimes when trouble
shooting and you've got a engine that runs but just doesn't run well.

Second side note is that if you don't tighten the flywheel nut up
enough the flywheel key will shear the first time it's started.
