Help needed with sb 318

Off in a bit to pick up a set of plugs, points, condenser, rotor and some vacuum line from carb to distributor.

Also, the carb does not have a working choke. Not sure if this is a product of mixing apples and oranges (newer 83 block) and older pre-71 carb and ignition system, but what do you make of this setup?

Seems like it has the makings of an auto choke system, but nothing to match up with it on the carb? Or am I just not seeing it?
