Not the positive outlook I was expecting, but thanks for the honest answer. I thought these motors were bullet proof...could eat aluminum and crap thunder! I haven't attempted a complete teardown yet, but it may be time to roll up my sleeves and dive in. I've got too much time into this build to quit now. Though I'm definitely in the market for a replacement motor.

Any chance a couple of good flushings, several oil changes and filters may get me a few years out of this old girl?
