Product Description

The BRIGGS STRATTON 690689 is a governor spool designed as a replacement component for small engine governor assemblies. The governor spool is a mechanical part within the engine speed control system, responsible for regulating throttle response based on engine load and RPM.

This part is intended for installation by small engine technicians and qualified service professionals performing governor system repairs.

The 690689 governor spool is used in small gasoline engines commonly found in residential and commercial lawn and garden equipment, including walk-behind mowers, riding mowers, and similar outdoor power equipment. It is a direct OEM-style replacement part sourced from BRIGGS STRATTON, suited for governor assembly rebuilds or individual component replacement during engine service.
