Another #7042240 Buick 800cfm Rochester Quadrajet. The other numbers are MB 0122. This one is also going to need restoration, but would make a good core. All the linkages work fine and aren't bent, however the larger choke butterflys seem a little sticky, which is probably just from built up carbonation. The thread inlets are dirty, but look good and are not stripped out. The forward vacuum diaphragm is broken and will need to be replaced, as shown in the pictures. I am unsure of this carbs history, I dont know if it was removed from a running engine or not. Asking 60$ plus shipping, I am located in Billings, MT.
