One New Aftermarket Replacement Governor Spring for Tecumseh 4-Cycle Engines

This governor spring is a direct replacement for the mechanical governor assembly on Tecumseh LAV-series 4-cycle small engines. The governor spring regulates engine speed by maintaining tension on the governor linkage, keeping RPM stable under varying load conditions. Commonly found on walk-behind lawn mowers, tillers, and other outdoor power equipment powered by Tecumseh engines.
