Default Magneto Repair vs Overhaul Question.

You can't call it an overhaul unless you perform the operation in strict
conformance to the manufacturer's (or tc holder, or stc holder or ...)
overhaul manual or instructions. In this case, since the manufacturer's
manual (according to the OP) requires the replacement of ALL components,
simply doing a points, bearings, and seal is a repair, not an overhaul.

I've done about as many engines as the next guy, and I can tear that sucker
down, replace every part in it to BETTER than new limits, reassemble it
perfectly, and since this particular manufacturer/engine OH manual requires
run-in in a test cell with a club prop and I don't have either, it is simply
an expensive repair, not an overhaul.

Sounds like they could call it an overhaul, unless Slick has a CMM or
other document that requires replacement of all of
the parts you are referring to.
