This product is the chainsaw's engine cylinder, which holds fuel ignited by the spark plug. It fits into the existing chamber and houses the pistons during use. It is attached to the carburetor for fuel injection. The spark plug is set within it to ignite the fuel. This part has to be screwed securely into place prior to use and requires lubrication for the engine to run smoothly. If the engine suffers from poor fuel ignition, or leaking fuel, the cylinder may be cracked. When installing the new part, a few holes may require a tap to fit each specific machine. Pistons and bolts sold separately. Existing parts should be cleaned prior to use. This OEM replacement part is sourced straight from the manufacturer and works with certain models of Poulan and Husqvarna small engines.
