A-B1594920-AI KIT-GOVERNOR/IDLE SPRING

One New Aftermarket Replacement Governor and Idle Spring Kit Fits Briggs and Stratton (B&S) Small Engines

This aftermarket replacement governor and idle spring kit Fits Briggs and Stratton small engines used in a wide range of lawn and garden equipment including riding mowers, zero-turn mowers, walk-behind mowers, and outdoor power equipment. The governor and idle spring assembly works within the mechanical governor system to regulate engine speed at idle, maintain consistent RPM under varying load conditions, and help prevent stalling. Springs in this system can stretch, fatigue, or break over time, causing erratic engine speed or loss of throttle control. Replacing the governor and idle spring kit restores proper speed regulation and smooth engine operation.

Important: Fits Briggs and Stratton governor spring kits are engine-model-specific. Verify compatibility using your engine model number, type number, and code number before ordering.
