Description
Overview:
The Keeper Valve for Briggs & Stratton engines (Manufacturer Part Number 807683) is a Genuine Briggs & Stratton OEM part. Made from hardened, wear‑resistant steel, this small but critical component locks the valve spring retainer onto the valve stem to maintain correct valve spring tension and alignment. This ensures reliable sealing, smoother running, and consistent performance under heat and vibration. It is suitable for a wide range of Briggs & Stratton single- and twin-cylinder engines used on lawn tractors, mowers, generators, and compact construction or garden machinery, including models such as 305440 and 305442. Designed as a like-for-like replacement, it restores the integrity of the valve train during routine maintenance or engine rebuilds without modification.
