I am in the process of installing the driver's instrument panel in my 3.8 FHC and have come to fit the choke cable.
I have measured the cable travel produced by moving the choke control throughout its full travel at around 1¼" (32mm). At the same time, I have measured the movement of the choke lever on the centre carb (where the cable inner connects) to be around 5/8" (16mm). Pretty much a 2:1 ratio.
I get the feeling that I have missed something somewhere (or something is missing) because the dash control is not going to go full travel under these conditions.

All words of wisdom gratefully received.
