11. After the engine has warmed up to operating temperature, adjust the idle mixture and idle speed. Check for full choke off position and choke operation. Adjust choke element by loosening the 3 choke ring screws and turning the element in the proper direction, depending on your specific desire for early choke off or longer choke on timing.
Oho!! But our very own Autoist, Tony, has posted the following.

A couple of things you may want to do before bolting the carburetor on are: Set the idle adjusting screw, #56, by turning it in until it seats and backing it out 1 1/2 turns. Further adjustment is usually required when the engine is running, but that will get you started. The other thing is to adjust the automatic choke when so equipped. Loosen the choke housing screws and set the carburetor on a flat surface so the throttle linkage is off the edge of the table or whatever. Open the throttle and turn the choke housing until the choke butterflies, #5, close. let the throttle close and don't touch it until you're finished setting the choke. Now, open the butterflies with your finger and pull it away quickly. The butterflies should close completely, but rather softly with only a soft click, not slam shut like a rat trap. Adjust the choke housing until you achieve this effect and tighten the housing screws. This is often the only choke adjustment you'll have to make, but each car is an individual and you may have to re-adjust in actual use. A lean choke is indicated by coughing and sputtering on acceleration when the engine is cold. A rich choke is indicated by blubbering and lumpy idle when the engine is cold. To adjust, loosen the choke housing screws only enough to allow you to turn the choke housing and move the index mark on the housing 1/32 to 1/16 of and inch richer or leaner as you see fit and try it again when the engine is cold.
