A manual choke works by restricting the airflow into the engine's carburetor, enriching the fuel-air mixture to facilitate cold starting. When the choke is engaged, a valve closes, reducing the intake of air and allowing more fuel to enter the combustion chamber. This richer mixture helps the engine start more easily in cold conditions. Once the engine warms up, the choke can be manually disengaged to restore normal airflow.

To use the manual choke on a Generac portable generator, first ensure the generator is on a stable surface and the fuel tank is filled. Set the choke lever to the "choke" position to restrict airflow, which helps start the engine when it's cold. After starting the generator, gradually move the choke lever to the "run" position as the engine warms up. Always refer to the owner's manual for specific instructions related to your model.


When do you need to use a manual choke on a car?

If the car has fuel injection you cannot use a choke. however if the car has a carburetor without a automatic choke that is when add a manual choke cable to the carburetor choke flap. When you pull the choke flap closed it limits the air flow to the engine allowing for the engine to warm up so so it can atomize the fuel for the engine to run more efficiently. This is important in cold weather you almost always have to use a choke to start the engine.
