One cable has two knobs on it. Which one is it? I had taken them out of what I think the manual calls the actuator. It has two wheels inside and a cable connected to the cruise control. The bottom wheel has two slots on it labeled 3 and 4 for the knobs on the cables. The top wheel has a slot for the cruise cable. The drawing in the manual doesn't help. Is there not a diagram somewhere? The manual illustration of the carbs shows number 1 which has two knobs as close side. Does close mean return? Number 2 is called open side. Does that mean primary? I just can't figure out where the two knobs connect to and where on the actuator wheel the cables connect to.
