Seems that Kevin's carburetor is also missing the fast idle link, the choke trip lever (that's the part in Tinman's photo), and the choke piston link. If the fast idle link is AWOL then the choke connector rod is also likely missing. The link and rod should have been visible in Kevin's 'Finished rebuild 2' photo in post 456, but they are missing.
It looks that what the carburetor was configured with a manual choke a lot of Carter's automatic choke hardware was removed. My immediate concern is the loss of the high idle feature. There may be climate conditions where the engine will start but either immediately stall, or run really rich because the throttle is not reset to high idle during warm-up. Kevin can ultimately determine when unloading is necessary, so in my mind that Carter hardware is optional.
I've attached a file containing the US Patent 2,402,361 (see Tinman's photo). The operation of the automatic choke, fast idle, and vacuum/air flow/full throttle unloading are discussed in the disclosure.
