This DIY riding mower repair guide gives step-by-step instructions for rebuilding the carburetor on a riding lawn mower. The carburetor blends air and fuel to produce a combustible mixture for the engine cylinder. If the carburetor runs rough because it's clogged or dirty, you can clean and rebuild it, using a manufacturer-approved replacement kit. The kit includes gaskets, seals, a hinge pin and other components that you might need to replace to fix riding mower carburetor problems. You probably won't use every part in the carburetor kit. In this repair, you use the fuel bowl gasket, mounting gasket and hinge pin to fix Craftsman riding mower carburetor problems.
Use these steps to rebuild the carburetor on common Briggs & Stratton engines that power Craftsman, Troybilt, Husqvarna, MTD, Poulan, Toro, Murray, Snapper, Yard-Man and John Deere riding mowers and lawn tractors.
If the riding mower carburetor is too corroded, dirty or damaged to rebuild, you can replace it with a new one. See How to Replace a Carburetor in a Riding Lawn Mower.
