Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This governor link is compatible with the following brands: Midwest Engine, Briggs & Stratton, Toro, Cub Cadet, and Simplicity. This part is sold individually.

This is a replacement air vane designed for use with a wide range of lawnmower engines. In order to operate, an engine needs both air and fuel. Those also need to be in the right proportions at different times during engine operation. For instance, when first cranking a cold engine, the choke must be closed to prevent air flow, but then the choke must open to allow airflow as the engine increases speed. The air vane pulls the choke open to allow proper airflow. The air vane is made from plastic. As such, it may degrade over time through exposure to high heat. Eventually, it may crack and break. If the engine does not stay running, it may be due to a damaged air vane that no longer pulls the choke open. Replacing a damaged air vane will require a wrench and a screwdriver. Remove the starter rope, discharge chute, gas tank, and engine shroud. Remove the damaged air vane and replace it with the new one, then reassemble the mower. This is a genuine OEM replacement part and is sold individually. It fits Briggs & Stratton engines and is used on Toro and Lawn-Boy mowers.

This is a spring that applies tension to the air vane on Briggs & Stratton lawnmower engines. It’s designed to return the air vane to a closed position when the throttle is closed and allow it to open wider as more air is required. This ensures a proper mixture of air and fuel inside the carburetor. Under ordinary circumstances, the air vane spring should not need to be replaced. If the air vane is violently pulled past its standard maximum point, the spring can be damaged. It can also become damaged over time due to corrosion, particularly if the lawnmower is stored outdoors. Replacing the spring is a simple matter. Just remove the old spring, then install the new spring in its place. With most models, no further disassembly will be required. On some other mowers, you may need to remove the carburetor or motor housing to access the air vane spring. Since it has universal applicability, this air vane spring is used on other engines from Toro, Lawn-Boy, and even Cub Cadet. This is an OEM part sourced directly from Briggs & Stratton, and it is sold individually.
