Have been hearing a lot lately about eliminating the divorced choke in favor of an electric choke. Does anyone have any experience with this conversion? I think my bi-metallic choke coil is beginning to fail....it's 50 years old!

Be sure all the choke linkage is free. Converting to an electric choke takes electrical work and some seemingly intricate work on the carb.

Have you seen a kit that is specifically made for this Cadillac carb?  I have seen universal kits that don't look as reliable.  The specific ones also look like a fair amount of work to install, there is drilling and tapping presumably of the carb to install them.

Mike's Carburetor shows they possibly have one.

Scroll down toward the bottom of the page and it shows part numbers CU1454 and CU1453 as possibilities, depending on whether Clockwise or Counterclockwise rotation is needed.  If you click on each one, and scroll down to the bottom of that page, it will give the carburetor numbers for that specific application.
