This is a great question as I was wondering the same thing....please let me add an additional question; Is there also a tightening screw for the gear lever? I believe I have to tighten my gear lever because when I engage it forward, I have to actually use a hand to push and hold it all the way forward to release the lock on the throttles, and then while holding the gear lever forward, use my other hand to move both throttle levers forward. Does that make sense? Would tightening this cable (if possible) relieve me from having to do this?
