Hi All, of the several listers using gear reduction starters, has anyone
ever needed to shim the starter back from the engine plate to keep the
drive gear and the flywheel from touching??  I did a trial fit of my
gear reduction starter with my engine on the work bench.  It looks like
the drive gear touches the back of the flywheel thus needing a shim of
about 1/16" or so to clear with comfort.  Something tells me this can't
be good.  Has this happened to anyone else??  Also, there doesn't seem
to be any chamfer on the starter drive gear.  Is this necessary since
the flywheel gear ring is chamfered on the wrong side for this type
starter.  Also again, does the drive gear start spinning immediately or
does it engage the flywheel ring first??  What's the concept here??
I'd love some feedback on this from the awesome storehouse of knowledge
on this list.  As always, many thanks.

Jack
