I am struggling with the resistance felt in my throttle cable. When the cable is disconnected from both ends i can easily move it by hand. When I connect the cable to the control box or hot foot it moves easy and returns as expected. I can move the throttle linkage on the motor with little resistance by hand. But when I connect the cable to the throttle linkage on the motor it is very hard to move and will not return to zero throttle position. (if that makes any sense).
