The 4762 has been media blasted. Part numbers CS 4760 with manual choke and 4762 choke less. Both are rebuild able cores with all critical parts intact. Both will need gaskets, needle and seats, jetting accelerator pumps.
The 4760 is missing several screws in the choke blade shaft. This is a rare pair of Carter Competition Series 750 cfm carburetors that are designed to be used in dual Quad applications. Both have been cleaned in a commercial ultrasonic cleaner.
