I'd like to try a new Zenith replacement carburetor but I'm not sure if I should get the 13922 or the 14991. I understand that the 14991 needs more work to hook up the choke but is the mounting bolts center to center distance correct for the model A? Any reason that the 14991 is a better choice? Anyone have experience with these carbs that could offer some advise?
Thanks.

I looked up the carbs, the 14991 is for tractors or engines that run at a set speed. That might mean it's does not have an accelerator well and might stumble if used in a car.

Thank you guys for your replies. Are there any folks here that have tried these carbs?

Why not stay with the Original Zenith, Built correctly and tuned right they perform well.....

I'm running the 13922 on my roadster. No problems and no more fiddling around with a GAV valve.

Bringing this back to life. Did anyone ever come to a conclusion as to which of these carburetors is better? One is small and was intended by Zenith to be used specifically for the Model A. The other seems larger and was intended as a universal replacement for many original tractor carburetors. Steve S, how did your testing go?
