The Carburetor Body Assembly in the M40 engine is an inseparable assembly that features features a machined carburetor casting that houses a jet press-fit into its body. The carburetor body incorporates a venturi tube, which creates a pressure drop to draw fuel from the fuel tank and mix it with incoming air to form the required fuel-air mixture. The jet, press-fit into the carb casting, controls the flow of fuel into the venturi, enabling fine-tuning of the fuel-air ratio to match engine demands.
