The flywheel key is the component on outdoor equipment that keeps the flywheel connected to the crankshaft. Over time, this key may become damaged or broken, particularly if the engine experiences a forceful stop, like hitting a large stationary object. If the flywheel key breaks, the engine will not start. A slightly damaged flywheel key is noticeable through symptoms like misfiring, backfiring, or having no power. If any of these are occurring, the flywheel key should be replaced to prevent complete engine failure.A flywheel puller tool is required for this repair. Make sure the engine is cool before working on the flywheel. Wear safety gear, including gloves and eye protection. Disconnect the spark plug and remove the blower housing. Remove the flywheel mounting nut and set it aside. Take the recoil starter cup off the mower. Use the flywheel puller to remove the flywheel and access the flywheel key.

This ring set is a genuine OEM replacement part sourced directly from the manufacturer. It is made explicitly for lawn and garden engines found on Briggs & Stratton machines. These rings are found between the walls of the cylinder and piston. The rings prevent combustion gasses from getting into the crankcase. Over time, the rings can become worn and damaged, causing loss of engine compression, power loss, and even total engine failure. Signs that the rings are bad include white or gray smoke coming from the exhaust, loss of power, excessive oil consumption, and low or no accelerating power. A ring expander, screwdriver, and socket set are necessary to complete this project. Remove the spark plug wire before removing and replacing the ring set to prevent accidentally starting the engine. Drain the fuel into a clean container. Remove the engine. Locate and remove the piston. Open the piston and remove the rings using the ring expander. Install the new rings in the same order the old ones were removed. Reinstall the piston top, and then reinstall all engine parts in the same manner. Install engine and refuel the machine. This ring set is made of durable metal and is sold as an individual part. The ring set is specially made for small engines manufactured by Briggs & Stratton.
