Also, just noticed the half link in that chain, it is also stiff, I think. I snapped one of those too... And what are those snail cams, they have a lot of adjustment - customized? I can see you had some troubles setting up your clamps/brake. I have that too on my stinger, especially with no washer clamps..., is that the only way out - half link? Or the ratio 17:14 would solve it, or some other one...
