I just put on a used 82# MG TM on my bow. The steering cables seem a little tight, so how do I adjust the tension. There are two cables coming out of the front of the pedal and they are enclosed in 2.5" long screw housing. I'm guessing I need to either loosen or tighten these screws to adjust the steering tension. If I'm right, which is it? Loosen or tighten?
