When starting an engine, the choke should be in the closed position. This restricts air supply, creating a richer fuel mixture that makes it easier to start the engine, especially in cold conditions. Once the engine warms up, switch the choke to the open position to allow a normal air-fuel mixture for smooth operation.

FAQs & Answers

  1. Why should the choke be closed when starting an engine? Closing the choke restricts air supply, creating a richer fuel mixture that makes it easier to start the engine, especially in cold conditions.
  2. When should I open the choke after starting the engine? Once the engine has warmed up and runs smoothly, open the choke to allow the proper air-fuel mixture for normal operation.
  3. What happens if the choke is left closed while the engine is running? Leaving the choke closed after the engine warms up can cause the engine to run rich, leading to poor performance, increased emissions, and possible engine damage.
