This Zenith 28IF carburettor is suitable for selected Renault R4 models produced between 09/1963 and 08/1986. The unit mixes fuel and air for the engine and supports a stable idle speed. The carburettor corresponds to the original dimensions according to PW1 sizing and fits within the existing intake system. Connection points for fuel line and throttle cable match the original layout on these vehicles. The design supports reliable engine operation under normal running conditions and serves as an appropriate replacement within the existing fuel system where this type was originally installed.
