AnyFM tuner mechanics out there?

Perhaps  can shed some light on what's going on with my Mac MR 71?

Recently had the tuning dial cable restrung. Now I can't rotate the tuning dial to the right past 91.5! I can turn the dial all the way left. I popped the cover to inspect the cable, and don't see any obvious binding. For now I'm at least stuck with all the public stations I listen to.



Any idea what could cause the tuning mechanism to bind as described?
