One New Aftermarket Replacement Governor Spring Fits Briggs & Fits Stratton Engines
This governor spring is a key component of the engine speed regulation system on Fits Briggs & Fits Stratton small engines. It maintains proper tension on the governor linkage, ensuring consistent throttle response and stable RPM under varying load conditions -- preventing both overspeed and underspeed conditions on lawn mowers, riding mowers, and other outdoor power equipment.
