I disconnected the cable and the pedal and cable move freely. I disconnected the return spring and made no difference. Anyone have a 770 with this problem? Thanks

I'm assuming the angle of the cable/connections looks OK live every 24 hour block of time like it's your last day on earth

I'm assuming the angle of the cable/connections looks OK Look here first. The closer your cable hooks to the throttle shaft the more pedal effort you will have. Old, tired, and sometimes broke down.
