Need to replace the brushes in starter. Starter looked easy to remove after looking closer couldn't find an obvious way to remove. Don't want to make work that isn't necessary. I removed the 2 bolts toward the front of the starter and the nut holding the positive cable that comes from the battery. After that the starter goes into a part of the "case" and there are 2 bolts that go into the back of the case toward the back of the ATV that the starter goes into, but those bolts don't go into the starter. Any body know what I need to do next?
