What does the choke do?

Explanation:
A choke changes the fuel-air mix for starting a cold engine. By partially closing the air intake, it makes the mixture richer (more fuel relative to air), which helps the engine start more easily and run smoothly until it warms up. As the engine heats, you open the choke to return to a normal, leaner mixture. It isn’t about increasing idle speed, keeping the engine from starting, or powering the electric starter.
