Scott, Very nice work indeed from one machinist to another, what type of a racing car is the Zenith going on and what is the throat size? Will you be machining more of these elbows and attachment bolts, I believe I may need one of these in the future?

Below is a similar 1-5/8" Zenith aluminum racing carb with no provision for a choke, and the original bolt on aluminum velocity stack.

To all, thank you for your comments and for looking. After spending the time to do the work, it just seems the right thing to do to show folks (maybe younger folks) that things can be MADE rather than just bought (though this couldn't easily be bought) and that a guy can earn a GOOD living doing custom work and not sweat paying off a student loan!

David, I don't foresee making another one soon, as that took more time than I like to put into a single part, but since I needed it for myself, it was a good project. To your question, I honestly don't know what car this will go on right now, but I do have a U-6 (which provided the dimensional info for this part) which will eventually find its way to a RAJO "B".

throat size at the manifold? 36mm. It will get it's new venturi in the next week or two...I have to figure out what mm choke to put into the venturi plus I am waiting for a die to make an adjustable main jet for it, and then decide how I want to make the missing choke actuator mechanism (it's missing on both the U-5 and U-6, so don't have an example so will improvise) so it is headed back to the shelf for now. Plenty left to do before it comes all back apart for the actual rebuild.

that aluminum Zenith is really cool!
