I must be suffering from brain fog and need some help. I have a Manco kart and am wondering why the cable housing is adjustable up by the pedal? The cable is inside the housing and moves freely inside it. There are nuts that hold the housing in place by the throttle and it allows one to make fine adjustments to the position of the housing. I don't understand how this does anything. The housing seems to protect the cable yet it is adjustable, why?
