Does anyone have any experience running a Model A Carb in a T?
Is it a good idea?
Thanks,

Re: Model A Carb.
Its been done for decades; possibly even as soon as the Model A came out. The drawback is it is an updraft carb, requiring a custom or an updraft intake manifold, usually requiring a corresponding exhaust manifold. This is pretty easily solved, but the harder drawback is the choke and throttle linkage modifications required. Lastly, a Zenith Model B carburetor is a far superior carb to a Zenith Model A carb, as far as performance goes, because of a modification that Zenith made to (if I'm not mistaken) the acceleration circuit in the carburetor.
BTW: There were at least 3 different model of the Zenith Model B carb made by Zenith. At least two were made for use with a fuel pump (which the 1932 Model B had) a standard carb and a high altitude carb, and one was made as a replacement for Model A's with a gravity feed fuel system.

Re: Model A Carb.
One of my customers runs Model A manifolds on all his Ts complete with Zenith or Tilletson (?) carbs and custom exhaust systems. They run great and are superior to the Model T set up and that includes the Stomberg OF that I use. Except for my requirement to be reasonably authentic, I’d run them as well.

Re: Model A Carb.
I have an updraft manifold that fits my T. I also used an original T exhaust manifold with it when I ran it. I now have a custom built single downdraft set-up on one T Speedster and a "Zenith" dual downdraft set-up on another T Speedster. All three run great.

Re: Model A Carb.
There used to be an old guy here who ran an SU off a 1960 Morris Mini along with the Mini distributor running horizontally from a bicycle chain drive. Went very well.
