The carburetor insulator gasket, or intake gasket, sits between the carburetor and the combustion chamber of a gasoline powered engine. This gasket provides a perfect seal that serves two purposes: to keep the fuel/air mix in the carburetor from experiencing too much heat before entering the combustion chamber and to prevent air or fuel from leaking. This particular gasket is used in a variety of small gasoline powered tools, including one- and two-stage snow blowers, log splitters, and other engine applications. This gasket continually experiences air, fuel, and heat extremes during use, and over time, the gasket may become warped or so worn that it becomes ineffective, allowing leaks to develop. When an insulation gasket begins to leak, there are some typical signs, including a very hot engine, stalling, sputtering, lack of power, and unusually high gas consumption. The carburetor must be removed in order to replace this gasket, which sits between the carburetor and intake manifold. When replacing this part, it is best to use a gasket such as this one, which is a genuine OEM replacement part, manufactured to be identical to the original part. This gasket is compatible with machines offered by Craftsman, Cub Cadet, Yard Machines, MTD, and Troy-Built.
