Re: Uncle Max Carb Quality
Wow! Those are unusual. If the 22.2 ,I think I see, is representative of millimeter venture diameter those are between the 81 and 97 size and something new to me.
Fully agree with Uncle Max being high quality only. JWL |

Re: Uncle Max Carb Quality
I learned from Max that the 22.2 in metric translates into 81.When I Googled the 22.2mm to inches it came up .87. I have found the French 97's that are 24.6 and the 48's which are 26.2. Our fond friend Bruce Lancaster got that 24.6 from me a few yrs ago. The 24.6 are even rarer ,seen 1 other in last few yrs.Lots of 26.2's as they were military with a governor .Each carburetor also had a serial number stamped on the flat raised area of the bowl .Last pic shows the side of the bowl detail.FYI,Embossed on the side of the bowl under Zenith/Stromberg is this and below that "fabrique en France" (made in France)
Breveté SGDG From Wikipedia, the free encyclopedia Jump to navigation Jump to search Breveté SGDG on an Ariston music player Breveté SGDG was a French type of patent that ceased to exist in 1968. The name was a common abbreviation for "Breveté Sans Garantie Du Gouvernement“ (patent without government guarantees). Background France and Belgium maintained a system of simple registration of patents. It was believed that patents registered in this way are free from any liability from the government perspective. In France, the law of 1844 states that patents are issued "without prior examination, at the risk of the applicant and with no guarantee of function, novelty and merit of the invention also in terms of precision or accuracy of the description".[1][2][3][4] In Belgium, a similar regulation was in place in article 22 of the 1984 Patents Act,[5] and, as of 2019, is still in place.[6] Last edited by deuce lover; 07-27-2020 at 01:48 AM.

Re: Uncle Max Carb Quality
Here is a pic of the bases.I think he reused them as they(81's) have smaller venturi's.They originally have a vacuum port between the adj screws.

Re: Uncle Max Carb Quality
Some nuances: The bowls have 97 size major venturis; the bases are counterbored from the top to accept the bigger venturi, and use 81 size throttleplates. The bowls have no slot in the powervalve chamber, but instead have two bleed holes - a good idea to prevent crimping the leather of the 81 size accelerator pump. Factory jets are .038" with #69 powervalves. The bare bowl casting was noticeably heavier and weighs 2-1/2 ounces more than an original 81. Probably due to more modern pressure die casting. All the machine work is incredibly precise. Stout, tapered boss for the fuel inlet. Two or three vacuum holes in the base and bowl needed to be plugged for hotrod service. The crude kicker linkage was put in the trash. All in all, challenging and fun!

Re: Uncle Max Carb Quality
Just a note of interest too, is that the French Zenith has nothing to do with the old Zenith Carburetor Company that was in Detroit, MI. (Now in Abbingdon, VA)

Nice! Good job on those, good work
Only problem I would have would be, they are too nice to get dirtied up I'd display them in an old time Ford Parts Dept. display ! |
