OK non-nerds, move on before your eyes glaze over. These are snake-head views of the back of instrument/control panel of subject aircraft. Well, I don't really know how a snake would see this, but this is the view you get when you poke your handy dandy pocket universal electronic device up there where your head don't fit for'ard of the panel facing aft, set up to function as a camera, and push the appropriate button. The first photo is taken from aft of the control column or Tee, subject Tee being pushed full for'ard, and the second photo is taken from for'ard of subject Tee pulled full aft. Got it? The remainder of this narrative is in the comments under the following photos.
The cables emanating from the panel left to right control: starter, cabin heat, brake lock, and carburetor heat, The mixture control is further right the typical distance beyond that white backed hole you see half of on the right edge of the photo. The dark (open) hole between the brake lock and the carburetor heat and lower down is where the throttle control cable goes.
The big pulley hogging the view has its top pretty near the center of the top of the Tee and guides the aileron cables which you can find there, and you can see a bit of the vertical part of the Tee below the pulley. You can also see all the cables described in the comment for the previous photo. The carburetor heat looks like it touches the aileron cable on the right 1.5 inches or so below the pulley and the extra shiny cable you see near the right horizontal center of the pulley is the mixture control. Notice that you cannot see the hole for the throttle control cable in this view. That's because the throttle cable and the control Tee have MAJOR interference. A line extending from the center of the throttle cable hole perpendicular to the panel intersects the center of the vertical bar of the Tee, and the first 5.5 inches of that cable are quite rigid so that if the yoke is pulled full aft the aileron cable on the left is pushed over to the right and the vertical column of the Tee pushes the throttle cable to the left and throttle can be seen by the pilot to move angularly to his left on his side of the panel. The rigid part of the throttle cable we took out was bent and it was difficult to work the throttle control. The fix? Move the carburetor heat control to the next hole over to the right in this view (you can see it in the previous photo) and move the throttle to the hole vacated by the carburetor heat control. For that we need to buy another cable 6.5 inches longer. (Anybody need a standard Cessna 170A throttle control cable? I've got a very, very slightly used one available.) This is how the Cessna 170A was designed and this design has never been officially corrected. Here are some other comments on the problem:
