BRIGGS & STRATTON 699488 Engine Flywheel

The Briggs & Stratton 699488 Engine Flywheel is a rotating part that stores and retains energy when it is running. It is attached to the motor crankshaft and used to transfer momentum between the power strokes of the motor and maintain smooth crankshaft rotation. The flywheel is also used to start the motor and can include fins that are used with the flow of air to cool the engine, depending on the application. It is used to maintain a consistent crankshaft speed and minimize fluctuations, leading to more stable engine performance, smoother operation, and accurate power delivery between compatible systems.
