Judging Standards mistake / clarification

[Vin-tin]

I think I found a mistake in section 1-15.
It states that a zenith 1 carb was used from May 1929 thru Dec 1929, and a zenith 2 was used Feb 1929 thru April 1929.
Since when did the zenith 2 come before the zenith 1?

Zenith 1 carburetors were made by "Zenith", Zenith 2 carburetors were made by "Holley", and Zenith 3 carburetors were made by "Ford". The numeric notation, "1", "2", or "3" had nothing to with chronological sequence of manufacture.


Look at the tables on page 1-12, and 1-13 revised 2011 under Carburetor Bowl assembly which specifies the markings on the bowl assembly.

hope this helps

Thanks for clarifying that for me.
My October 29 coupe came with a Zenith 2 (made by Holly). According to the graphs, my carb is correct in all aspects except one area. It has the zenith-2 "raised", instead of recessed.
So if i'm reading it right, I should have a zenith 1 to be "correct".
I guess I restored the wrong carb.

"I hate them querys" (Peter Falk as Det. Sam Spade in Murder By Death, funny movie!)

So, carbs with an 'H' for Holley were only marked that way thru the summer of '28? Even after Ford went to the single venturi??

The table on page 1-13 Revised 2011 under Carburetor Bowl Assembly, H in raised letter in the bowl area was from Dec 1927 - March 1928

Your October 29 could have a Zenith 2 in recessed letters or a Zenith 1 in recessed letters, look at both tables, one for the Zenith and one for the Holley.

Keep in mind that in the 30's and later when the carburetors were rebuilt the rebuilder did not care about matching top to bottom, he had a bunch of cores and put them together as he saw fit.

So who's carb is better? Zenith or Holly.
I should be good if I get a recessed letter zenith bottom?

They are basically the same, some will voice a preference one way or the other, but that may be a result of the quality of work that went into the rebuild.

Yes all you need is recessed letters as long as the upper body assembly is correct per the tables on page 1-12, and 1-13.

The Zenith 2 in raised letters was only used the first 4 months of 1929.
