Briggs Stratton 691816 Governor Spring Small Engine

Product Description

The BRIGGS STRATTON 691816 is a governor spring designed for use in small gasoline engines. The governor spring connects to the governor arm and throttle linkage assembly, applying tension that controls engine speed by working in tandem with the mechanical governor system. When the spring loses tension, stretches, or breaks, engine speed becomes erratic or the unit may surge under load. This is a direct OEM replacement part sourced from Briggs and Stratton, intended for installation by small engine technicians and qualified power equipment service professionals.

This governor spring is used in small engine applications where a mechanical governor regulates throttle position to maintain consistent RPM under varying loads. Typical installations include walk-behind lawn mowers, riding mowers, garden tractors, and other outdoor power equipment powered by Briggs and Stratton single-cylinder and twin-cylinder engines. It is a wear-and-service item commonly replaced during governor linkage inspection, carburetor service, or surging engine diagnostics.

Key Features

• OEM replacement governor spring from Briggs and Stratton
• Restores proper governor tension for stable engine speed control
• Designed to integrate with the existing governor arm and throttle linkage without modification
• Suitable for use across a range of Briggs and Stratton small engine platforms
• Direct fitment replacement reduces diagnostic guesswork during governor system repairs

Compatibility

Designed as an OEM-style replacement governor spring for Briggs and Stratton small engines. Consult the Briggs and Stratton parts lookup using model, type, and code numbers from the engine shroud to confirm fitment before installation.

Installation Notes

Installation is typically performed by a small engine technician or qualified power equipment service professional. Before servicing the governor linkage, disconnect the spark plug wire to prevent accidental engine startup. Governor spring replacement requires careful attention to linkage routing and hook orientation, as incorrect assembly will result in improper speed control or runaway engine conditions. Refer to the applicable Briggs and Stratton service manual for the specific engine model before disassembly.
