If the choke is stuck on, it can cause the engine to run rich, meaning there’s too much fuel in the mix. This can lead to poor fuel efficiency, difficulty starting, and unstable idling. To fix this, inspect and clean the choke mechanism. If debris or corrosion is found, it should be cleaned off. Sometimes, lubricating the moving parts or adjusting the choke linkage can resolve the issue. If these steps don’t help, it might be time to replace the choke assembly.
