The carburetor is an important component of any engine, as it helps to contain the flow of air that goes into the engine. If you are having trouble controlling the speed of your Craftsman lawn mower, or if the mower won't move as fast as it should, you may have something wrong with your carburetor. You can manually remove the carburetor at any time to see if it needs to be cleaned or fully replaced. You can purchase a new carburetor part from an online retailer or from a Craftsman manufacturer.
