This is a replacement carburetor used with a wide variety of lawn and garden equipment. It includes the full assembly for the carburetor and is responsible for mixing air and fuel together before both are transferred to the engine's combustion chamber. If the carburetor is damaged, the engine may not start as expected, even when the fuel tank is full. Carburetors can also become clogged by dirt or other debris.If the engine is not starting as expected and there is plenty of fuel in the tank, the best thing to do is test the carburetor for problems. This involves adding around a teaspoon of fuel to the carburetor itself after removing the air filter. If the carburetor is the problem, the engine should start but will quickly shut off. A socket set, pliers, and a screwdriver will be needed to replace the part.This carburetor is an authentic OEM replacement part that is directly sourced from the manufacturer. It is sold as an individual product. The carburetor is designed to fit generators and wood chippers created by Briggs & Stratton, Craftsman, Simplicity, and Tecumseh.
