This genuine OEM replacement part is a rebuild kit of various gaskets used in a gas-powered leaf blower engine. This kit includes a crankshaft gasket, a carburetor gasket and carburetor adapter gasket, a cylinder base gasket, and a muffler shield. Gaskets act like a seal between different parts of an engine that keeps different liquids and gasses from passing into the wrong section of the engine. Gaskets can become worn out and crack or shrink over time through repeated use and exposure to exhaust and heat in the engine. A common sign of a fault gasket is if your engine is not running at full capacity or if it stalls out shortly after ignition. Changing out a gasket should not be a difficult job, but it will depend on which gasket you are replacing. Making this repair will require a screwdriver and set of pliers. This gasket rebuild kit is compatible with Poulan, Weed Eater, and Husqvarna gas powered leaf blowers. These gaskets are made of a mix of plastic and rubber. This kit ships individually and is sourced directly from its original manufacturer.

The piston ring provides a seal between the cylinder wall and the piston, attaching inside the groove around the piston directly. It is responsible for keeping the combustion gases in the cylinder and preventing them from entering the crankcase.

This creates poor compression in the cylinder and can result in a loss of power to the equipment. Significant leaks could result in an engine that won’t run at all.
