   So, should I punch a hole through my new core? :)

But I have never had any kickback with my '3 which is
set at the usual advance.

Just a WAG, but this may be exactly why the static timing on a '3 is so
late, compared to other engines.  4 degrees is a mighty small angle, so I'd
guess that even if the cylinder did light off, the inertia of the crank and
flywheel would still carry it over to the power side of the stroke.

Come to think of it, that might explain that huge flywheel, too.

The other purpose of the huge flywheel might be to counteract the effects of
compression which will tend to push back.  Get that flywheel inertia to carry
on through the compression stroke.
