Important Fitment Note
Confirm that the carburetors are the Zenith 40 TIN type and that the service requirement covers a pair of carburetors. Verify the ST3947 identification, gasket geometry, bolt-hole and passage layout, and any applicable thread, seat, flange, or sealing-interface details against the carburetors being serviced. Compare every replacement gasket with the removed component before installation, particularly where similar-looking pieces serve different fuel or air passages. Verify the carburetor code, interface geometry, and removed gasket before fitting.
