Ted,
Thanks for your good advice. There is a question I still have. My sprocket is curved and I have it mounted so the teeth are away from the spokes. Is this the right way, or should the teeth be nearer the spokes? A reason i think I may have the sprocket backwards is that when I first installed it, I incorrectly left the outside fiber washer off, which would put the teeth closer to the spokes. It worked fine until the spokes gave out.
