Electric choke on those is nothing but a bimetal strip in a coil shape. Heat makes it uncoil, cold makes it coil tighter.

12V from the ignition heats the coil slowly. It takes perhaps two-three minutes for it to go from fully coiled (choke on) to fully uncoiled (choke off) just from the ignition being on. The single wire connects to any source that's 12V only when the ignition is on.

Heat from a warm engine, or just underhood temp on a hot sunny day, keeps it uncoiled for a good while after the ignition is off again.

It's adjustable by loosening three screws and then rotating the electrical unit. Obviously set it so the choke opens fully with the engine warmed up. You can play with how long it stays closed -- there's a fair range of adjustment that will still result in it opening fully when warm.
