Thanks Elliot and Adriatic.
Yep, I took the whole mechanism apart twice to figure out how it works. That #1 part was a major pain to put back inside of the arm for Bugs. It also has a flange to keep it from dropping too low. Also, the arm for the cam would stay on top instead of underneath. Even when I finally got it right, it still needed a tiny bend to ensure the pawl would advance enough to catch the next tooth.
