If the clock positions are identical (both links join the carburetor arm at the same degree of rotation) the motion ratio between the throttle linkage and the TV linkage will be exactly the proportion of the distances from the link attachment point to the throttle shaft center.
Example only: the throttle cable and TV cable both attach at 11 o'clock (slightly forward of vertical). The throttle cable is located 2" from the throttle shaft, the TV cable is 1-1/2" from the throttle shaft. The TV cable's motion is 1-1/2" / 2" = 75%. The link closer to the shaft is always slower.
However: if their clock positions differ, the link closest to 90 degrees from horizontal will always move fastest.
