How to Rebuild a Rally Lawn Mower Carburetor

The Rally lawn mower is a push-style lawn mower manufactured by Murray. The Murray Rally is powered by a single spark plug and a gas engine. It is a 22-inch self-propelled mower. The mower requires regular maintenance. Even if this maintenance is kept up the fuel lines and carburetor can still get clogged up. Old fuel, or debris in the fuel can clog fuel lines and build up as residue inside the carburetor. When this occurs, the carburetor has to be taken apart to be cleaned.
