Thanks for the information. A couple things. Where the cable makes it's transition from the cam to module is one place to keep an eye on for serving wear. Mine are the same way on both my Ryteras. It's not bad, but I do keep an eye on the servings in that location. The screw in my draw stop was a little long just as you desribe. I never thought about using a washer myself as it would have to be small enough to fit inside the head of the draw stop. I just put mine in a vise and filed it down about 1/16" and all is well.
Wish you luck with it now that you've changed it. It never hurts to experiment and find out for yourself just what is what.
Now that I think about it a small thin washer between the draw stop peg and the cam would serve the same purpose as filing the screw down. I guess that's what you did. Simple and easy.
