    I think I figured it out gents I had a crazy thought and disconnected the tach lead off of the negative side of the coil and wouldn't u know it the motor runs great.  It's an older sunpro tach that must be shorted out.  My starter still screeches but that must just be a conicedence.

    A shorted Sunpro tach? That's all it was? Wow you are lucky! Nice job finding the problem, I hope this motor run well for you! Congrats! :2thumbs:

    Now you know why the other motor was running rough, or is there more to the story. Glad you found the culprit. :2thumbs:
