What your arrow is pointing at is not the choke that is an idle solenoid. The choke will be right under the threaded rod for the air cleaner. It looks like it is there in the pics but I can't tell for sure. the shaft closes to the top will be the choke shaft. the small linkage rod on the back of that shaft should go to the throttle butterfly and the one on the front of that shaft should go to the Intake manifold and have a bi-metal spring under a small cover. The spring is all that controls the choke. There are a few other carbs that will fit that engine without too much trouble. My old 292 had a Model 1940 Holley on it. worked well. About any single barrel rochester will fit but the linkage is the hard part to adapt. You may be able to put a cable choke on the one you have but it may involve fabricating a bracket for the cable housing and getting one of the little brass endpieces to activate the choke. Sorry if that wasn't much help. I don't have any of these carbs around anymore or I could maybe help with some parts.
