OK... so I have a 1996 Polaris 500 4x4. It was working fine it had a little bit of problems holding the battery though. So I would have to pull start it but one time when I pull started it the string wouldn't go back in but it started and it started to make a loud clanking/grinding noise from around the pull string area just sitting there I wasn't riding it or anything but it started doing that out of nowhere? Could I have broke the gears or what?
