Carburetor part wanted

[Skygeezer]

I am looking for a 30 mm venturi for a Model 11017 Zenith carburetor. Any information on where I can buy one will be greatly appreciated. I have found many places that sell carb rebuild kits (gaskets, floats, needles, etc) but none that sell the venturis. I understand that the venturis may be interchangeable for various Zenith models, so if anyone has one from another model, I would like to investigate that. Thank you.
