Move the choke to the closed position when starting a cold engine. Once the engine starts and warms up, gradually move the choke to the open position to allow the engine to run efficiently without restricting the air flow. This ensures smooth engine performance and prevents stalling during operation.

FAQs & Answers

  1. Why do you need to use the choke on a cold engine? The choke restricts airflow to enrich the fuel mixture, helping the cold engine start more easily.
  2. How long should the choke stay closed after starting the engine? Keep the choke closed until the engine starts and begins to warm up, then gradually open it to allow normal airflow.
  3. What happens if you don’t move the choke after starting a cold engine? If the choke stays closed too long, the engine may run rich, causing inefficient performance and potentially stalling.
