The number on the bottom casting is (in all probability) a part number for
the casting. The carb number in the application tables is on a little
aluminum (aluminium for you IIRC) tag attached by a top cover screw. These
tags are most often missing.

The 65 carb can be identified by asymmetrical venturi cluster, power
enrichment valve, and no extra screw in the throat, as per Bob Helt's book.
So ignore the casting number and proceed as they are most likely 65 carbs.

Gentlemen,
                  I have been given a Corvair motor which has not been 
run for more than twenty years. Identification information suggests the 
motor to be a '65 110 HP, for manual transmission.  I would like to 
re-build the carburettors, and upon examination the number cast into the 
base on each carburettor is 7029332.

The carbs are in apparently excellent shape.  There is almost no 
discernible wear on the throttle shafts.

Using Bob Helt's excellent carburettor book, the carburettors are almost 
certainly 1965 components.  However, the number above does not appear in 
the application tables in the book.  Can anyone advise me, please, as to 
just what these carburettors were intended for?  Many thanks,

David Neale
