OK Folks,
I took the pulley's off. It was easy and I learned a bit. Below there should be 2 pic's of the two pulley's where they mate. I made a good guess as to the clutch material. On the driven pulley there is a ring of leather that goes up against a stop pin (see the tip of the screwdriver) and there is a flat cast plate on the outer side of the driev pulley's. It looks like my leather ring may be a bit worn but I'm going to try to adjust it to where it works for now.
