This replacement exhaust gasket is an authentic OEM part for a snowblower or lawn tractor engine. On these appliances, the exhaust is located quite near to the air filter, meaning that there is a chance that exhaust could leak into the carburetor. The carburetor requires fresh air to oxygenate fuel for combustion, so manufacturers install a gasket to help seal off the exhaust. Once installed, gaskets exist under a lot of pressure and will absorb the heat of the engine. These stresses cause gaskets to slowly degrade and eventually break their seal. If the exhaust gasket blows, the engine will not perform as it should. Be cautious of a noisy engine that burns more fuel than usual and gives off a burning smell. These are signs that the exhaust gasket has given out. If so, use a socket wrench and wrench set to disassemble the blower and air filter housings, then remove the exhaust manifold and change out the broken gasket. This high-quality replacement exhaust gasket is compatible with engines made by Toro, Husqvarna, Briggs & Stratton, and Snapper. It comes sourced from the original manufacturer and ships individually.
