Is a Carburetor Choke Open or Closed When Engaged?
Learn why the carburetor choke is closed when engaged, restricting airflow to help start a cold engine efficiently.
Video transcript
When you choke a carburetor, it is closed. The choke valve restricts the air flow, allowing more fuel into the mixture to make starting a cold engine easier. Once the engine warms up, the choke should be opened to allow normal air-fuel mixture for efficient operation.**
