carburetor gurus????

[richsfords]

After reading the articles in the Restorer's great edition of Guide to Zenith Carburetors.1-5
and still confused. there was only passing mention of Z-2s
I have a ZENITH -2 with a Z under the throttle throat, front side.
Back side has large "E" with small"44"above.
under on main body is "B5". have determined that its not a "Frankin"?
I have a early 31 S/W fordor. want to acquire the correct carburetor. I know that this one is not correct????
thank you all

Richard, I would suggest you break out the JS&RG and look at the carb differences for what you are looking for. I have found this to be the closest reference for month/year of carburetors.

Yes, the JS & RG is one of the "must have" books for every Model A owner.

There are a few carburetor books. I only have the one written by Steve Pargeter, and think it's excellent.

be there done that
no mention of the Zenith 2
yes I can find the correct Carb. but need infor about the one I got.

The carb you described is a kludge, with a Zenith top and a Holley bottom.
Very common to find like this after so many years.
Most found carbs have been tinkered with and a great many are mismatched.

Steve wrote the Restorer series on only the Zenith produced carbs.
He told me he is considering whether to do a series on the Holley Zenith 2 series.
Maybe, maybe not.

In the mean time, go to the RG&JS for the best advice on authenticity.
OBTW, Steve was also the major contributor to the most recent revisions of the carb Standards, so you are not likely to find much conflicting or different info.

Oh, and here I thought you were looking for the correct one, sorry.

There is a whole page on the Zenith 2 in the Standards 1-13 Holley Carburetor Casting Changes.

As stated , the Zenith 2 was virtually a Zenith 1 but made by Holley. A good book is the orange one by Paul Moeller which has a lot of info., photos, dwgs, etc. He states that the first 2's had raised letters, the later ones after 5-29 had steel fittings and recessed letters. We had an early SW without indented firewall and used a Zenith 2 (and no side bowl filter).
