One New Aftermarket Replacement Governed Idle Spring Fits Briggs and Stratton Small Engines
This governed idle spring is a key component of the throttle governor system on Fits Briggs and Stratton (B&S) small engines. It works alongside the governor lever and throttle linkage to regulate engine speed at idle, maintaining consistent RPM and preventing the engine from hunting or surging under light load conditions. A worn or broken governed idle spring is a common cause of rough idle, high idle, or engine speed instability on lawn mowers, riding tractors, pressure washers, and other outdoor power equipment powered by Fits Briggs and Stratton engines.
Compatible Equipment
Fits Briggs and Stratton Small Engines: Used across a wide range of Fits Briggs and Stratton (B&S) single-cylinder and twin-cylinder small engines found in walk-behind lawn mowers, riding lawn mowers, lawn tractors, garden tractors, pressure washers, and other outdoor power equipment. Verify compatibility against your specific engine model number before ordering, as governed idle springs vary by engine series.
