224 views

Leave the choke on only for the initial engine startup. Once the engine runs smoothly and can idle without stalling (typically within 30 seconds to a few minutes), gradually turn the choke off. Keeping the choke on for too long can flood the engine or cause excessive fuel consumption and carbon buildup.

FAQs & Answers

  1. Why should I not leave the choke on for too long? Leaving the choke on for too long can flood the engine, increase fuel consumption, and lead to carbon buildup which may damage engine components.
  2. How do I know when to turn the choke off? Turn the choke off once the engine runs smoothly and idles without stalling, usually within 30 seconds to a few minutes after startup.
  3. What happens if I remove the choke too early? Removing the choke too early might cause the engine to stall or run roughly because it hasn’t reached the ideal temperature for normal fuel-air mixture.
