the cam initially is 2" from the throttle center line and ends up at 1". This gives a very slow and smooth throttle opening. The cable is multi-stranded and teflon lined with rod ends at each end to retain the cable and allow for angle change. This particular design has a threaded stop for initial tension and is designed so that the pedal hitting the floor is the full open stop. I have some really big throttle return springs that would give mechanical linkage fits but work fine with the cable. It has a very nice smooth feel to the throttle now.

I have posted a picture of the throttle cam assembly that will give an idea of general shape.
