Morphology
The meaning is directly and transparently derived from 'automatic' (operates with little human input) modifying 'choke' (a valve controlling air to a carburetor): together they denote a choke that functions automatically. This adjective+noun composition is a common, literal device-naming pattern cross-linguistically, so a B1 learner who knows both constituents would understand the term.
Etymology
Automatic choke creates a simple image: a small part called the choke that partly blocks the air to help a cold engine 'start'. The word automatic shows it does this by itself, so the name means a device that helps the engine start without the driver doing anything.
