Description

This muffler gasket plays an essential but unappreciated role in the performance and upkeep of a small lawn engine. Between the muffler and the exhaust manifold, there is a tremendous heat exchange. The muffler gasket is meant to provide a seal between these two important parts of the engine. When the seal is compromised, exhaust can leak from the manifold. Not only does this create a new and unacceptable noise, but it directly impacts the combustion of the engine, which is designed to work with a well-attached muffling device. Since the gasket is a composite material and not made of steel or aluminum like the part surrounding it, it may wear out, experience cracks, and need to be replaced to assure the safety and performance of the engine. It is best to replace the factory original muffler gasket with an OEM certified manufactured part like this one that is guaranteed to match the specifications of the original. When removing the muffler, its condition should be carefully examined for rust and wear. If it's time to replace the gasket, the accompanying muffler might need to be replaced as well. This gasket is compatible with over 150 different engines, including those built by Toro, Honda, and Lawn Boy.
