The carburetor's air intake system includes a filter element that can be easily accessed and replaced. The filter helps to prevent dirt and debris from entering the carburetor and damaging the fuel system. The air intake system also includes a throttle valve, which regulates the amount of air that enters the engine, and a butterfly valve, which controls the fuel flow to the engine based on the throttle position.
The Weber 67422 is constructed from high-quality materials, including brass bodies and stainless steel components. The carburetor's durable design ensures long-lasting performance, even in the most demanding conditions. Additionally, the carburetor comes with a gasket kit, which includes all the necessary gaskets for installation, making the installation process easier and more convenient.
