C1 dual quad #'s

[Owen W.]

I have a set of WCFB dual quads. The casting # on the top is a 6-1151 and the main body is 1049. Could someone please tell me what year they are off. One has the choke and the other does not have any holes. Thanks

Looks like 56 and early 57 check the main body again should be 0-049

If they are 1956 vintage, they may be distinguished by a screw in the cast iron base that does not appear on any other model year. The screw is an idle air bypass needle valve. It would be located on the left side of the base (same side as throttle linkage) toward the rear on both carburator bases.
