yes I've worked on several, the first picture is of vacuum carbs, the next set of picture's are the one's sold with acc pumps for the mechical linkage. they worked . there is no way you could open the throttle with michanical linkage and vacuum linkage and not have it stumble or bog without acc pump putting in extra fuel unless you were at a high rpm. you can tell the carbs cause the fuel inlets were on the drivers side.
