Default Re: Model B Zenith Carburetor

Don't forget the power tube that the B carb has. Actts like an accelerator pump. Read up on it on Vince's site:

http://www.fordgarage.com/pages/bpowertube.htm

Over several decades I have tried Tillotson's, Simmons, Allstate, and lots of Zeniths but I have been using a Zenith B carb on my Tudor driver for a couple of seasons now and may not ever go back to my old stock Zenith. It is running on a stock A manifold. Plugs burn nice an tan. My perception of it is that I need fewer downshifts for going uphill. Easy steady top end power. You can also run with the GAV completely closed. This is the carb to use if you ever go to a dual updraft manifold.

Please do a search on Ford Barn of previous threads on B carbs. Lots of pros and cons already discussed on FB so it goes back to different strokes for different folks.
