The valve body assembly in the M40 engine comprises two integral parts that work together to regulate fuel flow within the carburetor. At its core lies the valve body, a precision-engineered component featuring a machined valve seat and fuel passages. The valve seat ensures a consistent seal, while the fuel passages facilitate controlled fuel flow into the engine. Complementing the valve body is a nylon over-molding, providing fuel connections through molded hose barbs and mounting accommodation for the valve body assembly. This over-molding ensures reliable fuel delivery and a secure connection between the valve body and the fuel lines.
