Ok maybe I did not say what I wanted to the correct way. My concern is the if you have the cable set to close to the pivot you will not have enough movement of the cable AND it may be causing a binding at the cable due to the way it is trying to pull the cable.
I guess I could have asked my question better and come up with a better way to try to help.
You are correct in that the longer the pedal is from the pivot the less force you need to move it.
If you have tried both a master/slave system and a cable system and both are hard to push it has to be the way the pivot is set up or a drag on the bearing.
If you get a moment call me so I can get a better handle on what is going on. I will be in the shop till 5:00.
