If the regulator operates, you can replace the roller and it's attaching rivet to fix the problem with the missing roller on the end of the regulator arm. Buoymaker's second picture shows a roller that's pretty much worn out. The new ones are available from The Filling Station (and probably other vendors), and are made of nylon. They come with the rivet. It's pretty easy to remove the original rivet and install the new one. I don't think a leather washer would last long.
