A tip for eliminating the interference of the throttle cable stop, preventing the throttle lever from returning to the idle position is to move it an inch below the throttle lever. There is no reason for it to be close to throttle lever. Nobody ever needs to pull the throttle knob all the way out.
Someone 86'd the throttle cable before I got the truck. When I bought the new one and hooked it up, I was told to leave it an eighth inch below the rod.
I suppose that an inch below won't matter since I rarely use it anyway and, as you say, it will still work but will have to be pulled a little farther out before it engages.
