How Does The Choke Work?

The choke is a device on a lawn mower which controls the amount of air and fuel that enters the carburetor. It is used to aid with starting an engine that is cold or has not been used in a while.

When you pull the choke out, it restricts the amount of air and increases the amount of fuel in the carburetor. This makes the fuel and air mixture richer and easier to ignite, allowing the engine to start more easily.

As the engine warms up, you push the choke in slowly to gradually allow more air into the carburetor and lean out the fuel mixture. The choke can malfunction due to a number of reasons such as dirt, debris, and mechanical failure.

Troubleshooting the choke requires a thorough understanding of the device and its functions.
