Am I measuring the length of the covering shroud which will be fixed at both ends, or the length of the inner cable which will do the actuation?
If measuring the covering, then I'd want to measure from the attachment forward of the throttle quadrant to the receiving bracket on the engine.
If measuring the inner moving cable, it seems to me that I'd want to measure from (for example) the throttle lever when fully aft to the lever on the servo when fully forward?
Or do I own that girl an apology?
