Here are the specs which came with my NAPA rebuild kit:

Series 63: 1 + 5/8"
Series 63M: 1 + 19/32"
Series 61-67-68-161-267: 1 + 5/32"
Series 263M: 2 + 1/64"
(Look at the tag on your carb for the series #.)

For my 1953 Super A, it was 1 + 5/32". It was also 1 + 5/32" in my IH SA Service Manual. However, that did not work. At best, it ran rich; at worst, it flooded out. I had to set it at almost 1 + 1/4" in order to get it to run lean enough. It ran like a dream after that.
In my 140 IH Service Manual, it lists all 123 engines equipped with Zenith carbs at 1 + 5/32".
