In the pics it looks more or less normal. You could try a band adjust to see if it makes any diff. Back off the lock nut (without moving the adjusting screw). Tighten adjusting screw, count the turns til contact with servo, then back adjusting screw out 2 1/4 turn. Tighten the lock nut (without moving the adjusting screw) I don't think it will make a diff. but you won't know if you don't try.

Good luck.
