Zenith Carbs All Manufacturers
I picked up a Zenith Sidebowl top which allowed me to pair it with the Zenith 3 bottom I already had. After I got done I realized I now had all 3 manufacturers quite by accident. I currently have a Zenith 2 sidebowl on my late 31 deluxe coupe and this Zenith 3 will be it's replacement unless I decide to sell it. I found the Zenith 3 bottom 4 or 5 years ago.

Re: Zenith All Manufacturers
The Zenith 3 carburetor top is distinguishable from the others as they are a thinner casting and there is some reinforcement on the top ears.

Re: Zenith Carbs All Manufacturers
It matches the 3 other Zenith 3's I have seen.

Re: Zenith Carbs All Manufacturers
None of the Carbs shown in Tincups pictures have the cast upper support under the mounting bolt hole in the one facing the rear of car as shown in Joops picture of the Zenith 3.. Both types of the 3s had that feature.

Re: Zenith Carbs All Manufacturers
Here is a photo from the RG&JS page 1-15 revised 2016. Note the difference between the ears on the carburetor on the left hand side and the carburetor on the RH side. The one on the right is a Zenith 3.
Look closely at the areas circled in the 2nd photo. Note for the carburetor on the left: Zenith carburetor castings used from January 1930 through April 1931. Note the alternate design top casting with a "knob" on the gas inlet passage. Note for the carburetor on the right: Typical Zentih-3 carburetor castings (flat firewall style shown)

Re: Zenith Carbs All Manufacturers
Well I guess I have more looking to do. I have never seen a Zenith top like the one pictured above and I have seen my share of Zenith Carbs. I have seen a half dozen Zenith 3's and they all have the top I have now. I guess a half a Zenith 3 is better than no Zenith 3 at all

Re: Zenith Carbs All Manufacturers
We rebuilt a side bowl carb for the late 31 truck. I am attaching the only picture I have on my phone. Angles and perspective are tricky, but it looks like the top pictured above. I know the bottom half is a Zenith -2. I will look closer at the carb when I go to the garage later tonight or tomorrow.

Re: Zenith Carbs All Manufacturers
Many Original Zenith 3's Tops have cracked from 87+ years of use and abuse and are now sporting Tops from earlier Zeniths.
Remember the 3's were an early attempt at saving money by casting the walls thinner and the reason for the added bracing on the flange.

Re: Zenith Carbs All Manufacturers
There is a box out in the garage someplace with five or six ZENITH shape carburetors in it. Remember looking at them awhile back and none were marked ZENITH. Had a real ZENITH ONE pulled off the 31' Ford to compare those but got rid of that thing on eBay last year.
Does anybody actually use those clone ZENITH carbs? With other much better carburetors available, why would any manufacturer back in the old days have made a reproduction of the troublesome ZENITH?
