I got a denso rebuild kit and took it to an electric motor shop. They rebuilt it and it works great. They said they couldn't believe it worked at all, it was a mess in there. It was super dirty and the brushes were almost totally gone. It was a napa starter and he said it looks like I got a good one, it was definitely used quite a while, I didn't buy it so I don't know how long it was on there. Well problem solved, thanks for all of your input. It still wasn't cheap though, I paid $50 for the rebuild kit and $150 for the shop to do it, but it should be as good as a new denso.
