Harvester,
Thanks a bunch for all of that! I disassembled the starter today and unfortunately the commutator is pretty chewed up, so I will just have a professional deal with it. There is an auto electric rebuilder less than 1 mile away from my house that has been in business for years and does great work. At least this way I know the starter will be as good as new. He goes through and checks everything to make sure it is right. If it isn't right, he makes it right.
