Hi Chad. Without seeing it up close I tend to think like a couple of others that the brushes may be beyond their lifespan and just being disturbed may have put them out of their misery. If you clean(ed) the commutator that the brushes ride on, make sure any copper dust gets cleaned out from between each little contact segment.
Don't know if you have any good old school electric shops up there. We used to have great one here on the Island, but they closed doors about 2 years ago. But a good old time shop should be able to refurb any kind of starter.
