I've already pulled everything apart and I managed to lose the piston pin clips, so I'll need to get those. The rings were pretty crusty, but might clean up fine.
I put the bike completely back together just to make sure I hadn't lost any parts. Only missing two screws for the air filter cover!
I'll take a look at the carb again. It has been a few years since I took it apart. It had been sitting for over 20 years before I took it apart. You can imagine what gasoline looks like after that long sitting in a carb.
