Does '73 electric choke need exhaust heat crossover in warm climate?

Worst case scenario, I'll rig up a manual choke. Actually, a manual choke would be my first choice.

Back in the day, I did this to several carbs, all had been well type automatic. "The thing" which for me made them work well, was to (sometimes) solder a tab to the linkage to make an approprate lever. Some already have something useable. Then get TWO "choke stop" like this:

I would take a longer screw and lock nut and attach that to the choke lever, "lock" that screw to the lever. You have to play with the length. Screw the stop on so that it still swivels and the hole is clear

Then stuff your choke wire through the hole on that first stop, add a small spring such as out of a ball point pen, and apply the last choke stop on the end. This allows you to pull the cable "a little" work the pedal to "set" the choke, and provides a sort of "non solid" connection. Worked very well when adjusted.
