Description
Overview:
The Governor Spring for Briggs & Stratton 575EX and 675EXi engines is a small but essential metal spring that controls engine speed by linking the governor mechanism to the throttle. As a Genuine Briggs & Stratton part, it is built for reliable performance and correct fitment on the specified engines. The spring maintains a steady governed speed under changing loads, helping the engine run smoothly without surging or overspeeding. Made from durable metal suitable for repeated flexing, it restores proper throttle response when a worn or stretched spring is causing poor running. Ideal for walk‐behind lawn mowers and other small petrol equipment using these engines, it serves as a direct replacement for OEM 691852 and supports both routine maintenance and repairs.
Key Features:
- Genuine Briggs & Stratton replacement spring for consistent quality and fit
- Direct replacement for OEM 691852 to simplify part selection
- Durable metal construction for long service life under engine vibration
- Helps prevent hunting, surging, and overspeed by stabilising governed speed
- Restores crisp throttle response after wear or stretching of the old spring
- Correct tension and length for 575EX and 675EXi governor linkage
- Quick, straightforward installation with basic hand tools
- Suitable for domestic and trade use where dependable engine control is required
