Re: choke setting
I don't know what you mean by "manual choke no fast idle setting", unless you mean that it is not adjustable. That is true. But the fast-idle cam on the choke actuator lever, although it is fixed/integral with the lever, you can achieve different idle speeds depending upon how much the choke knob is pulled out. And if you pulled out the choke knob all the way, the engine races in idle.
The choke actuator lever has a dual function independent of the accelerator linkage and idle adjustment. The lever activates the choke butterfly and as the lever pivots, the fast idle cam pushes against the accel lever.
I can't imagine anybody needing to pull the choke lever out all the way unless the temperature is sub-zero.
I once had a '57 Y-block. They all had automatic chokes. Mine would never disengage to fully open, so I ripped it out and installed a cheap manual choke conversion kit. Loved it.
