The standard choke uses a thermostatic coil that winds up the choke shaft
when it is cold, and unwinds it when it is warm. It is heated using a choke
stove, which is a loop of tubing that projects down into the exhaust
crossover in the intake manifold. A tube is connected to it and to the side
of the choke thermostat housing, which is the bell-shaped projection out
the starboard side of the carburetor.

The choke stove can rot out, sending exhaust gas directly to the carb
thermostat.

An electric choke works one of two ways, but both ways replace the choke
stove in the intake manifold. The method I prefer uses a temperature sensor
that is clamped under an intake manifold bolt, and an actuator that mounts
in the thermostat housing to replace the coil. It pulls the choke off as
the engine warms up. Both methods need power from the ignition circuit to
pull off the choke as the engine warms.
