Start with the choke closed. When you're starting an engine cold, closing the choke ensures a richer fuel mixture which helps ignition. Once the engine starts, gradually open the choke to allow more air into the mixture. After warming up, the choke should be fully open for normal operation. This process makes sure your engine starts smoothly and runs efficiently.

FAQs & Answers

  1. Why should I start my engine with the choke closed? Starting an engine with the choke closed creates a richer fuel mixture needed for ignition when the engine is cold.
  2. When should I open the choke after starting the engine? Once the engine starts, gradually open the choke to allow more air into the mixture, and fully open it after the engine warms up.
  3. What happens if I start the engine with the choke open? Starting with the choke open can make it difficult for a cold engine to ignite because the fuel mixture is too lean.
