Different Model A Venturi 6 Attachment(s)
..
Found this at a Swap Meet today. Same as Zenith but with brass insert. Does not look home made. What is it for. Thanks .. |
Re: Different Model A Venturi Looks like some sort of aftermarket venturi. Put it in a Zenith carburetor and see if it runs.

Re: Different Model A Venturi since venturi is smaller maybe it is for a British engine ...
Although Henry would have used all pot metal unless there was a manufacturing problem which required brass for the smaller opening. Brass was expensive |
Re: Different Model A Venturi If the inside diameter of the venturi is smaller it will restrict power .

The carburetor for the AF engines did have a smaller orifice venturi (and smaller jet orifices as well).
Here is an original, April 1931, document from Zenith, France indicating the size of the AF single venturi. See the blue arrow indicating that the venturi of the carburetor for the AF engine is "18" compared to the venturi for an A and AA engine is "21.5" (look under the "Diff" column): https://www.fordbarn.com/forum/attac...1&d=1569812928 "Diff" = Diffuseur, the french word for venturi So based on the measurements that you show of your mystery venturi, it seems like it is not a venturi for a Model AF engine.

Re: Different Model A Venturi Thanks for posting that info Brad
|
Re: Different Model A Venturi Yes I concur with Brad the smaller engine was 18mm dia venturi ( approx 0.7 inch). Suspect that the venturi in the OP is someone's experimentation.
