This DIY repair guide shows how to rebuild a leaf blower carburetor. The carburetor mixes fuel and air in the right proportions so that the spark plug can ignite the mixture inside the cylinder, powering the engine. If the leaf blower engine won't start even though there's fuel in the tank, the carburetor could be the problem. Clogged fuel and air passages in the leaf blower carburetor need cleaning when they get clogged. Follow these instructions to clean and rebuild a carburetor using a manufacturer-approved gas leaf blower part.
This guide shows how to clean and rebuild the carburetor on Craftsman, Poulan, MTD, Husqvarna, Weed Eater and Troybilt leaf blowers.
Another option is to replace the carburetor, following the steps in How to Replace a Leaf Blower Carburetor.
