One New Aftermarket Replacement Governor Spring Fits Briggs and Stratton (B&S) Small Engines
This governor spring is a critical component of the mechanical governor system on Fits Briggs and Stratton small engines. It holds the throttle at the optimal maximum speed after the governor adjusts the throttle in response to changing engine load, helping maintain consistent RPM, prevent over-revving, and ensure reliable performance under varying operating conditions. Common applications include walk-behind lawn mowers, riding mowers, and other outdoor power equipment powered by Fits Briggs and Stratton engines.
