I was hooking up the control cables and the distance between the slot in the cable end to where it clips to the motor is about 3/4 of an inch to short even turned out almost all of the way, the other cable is fine. In the swivel clamp with the 1 screw I have it tightened up on the rear of the cable metal, it that ok to do/ do they make any type of an extention part for this problem? thanks for any help on this subject.
