The carburetor's air cleaner base is designed to fit directly onto the engine, making installation easy and straightforward. It is equipped with a removable air cleaner element, which can be cleaned or replaced as needed. The air cleaner base also includes a provision for a temperature gauge, allowing you to monitor engine temperature for optimal performance.
