This DIY riding mower repair guide gives you step-by-step instructions for replacing the carburetor in your riding lawn mower or garden tractor. The carburetor blends air and fuel to produce a combustible mixture for the engine cylinder. If the carburetor has water damage or is clogged with dirt, debris or gummed-up gasoline, the engine might surge or be hard to start. Replace a damaged or clogged riding lawn mower carburetor with a manufacturer-approved riding lawn mower part.
Use this repair guide and video to replace the riding lawn mower carburetor on Briggs & Stratton engines powering Craftsman, Troybilt, MTD, Husqvarna, Murray, Snapper, Weed Eater, Toro and Ariens lawn tractors and riding mowers.
If the carburetor isn't beyond repair, you can rebuild it instead of replacing it. See How to Rebuild a Carburetor in a Riding Lawn Mower.
