Too Afraid to Ask

A choke is a part that helps a car start by making the engine run richer (more fuel) when it’s cold or idle. It closes off some air so the engine can start easier.

Technical Definition

A choke is a device in carbureted engines that restricts airflow to enrich the fuel mixture when starting or idling at low RPM.
