This is as good as it gets. An all original Master Carburetor, correct size for a Model T racer or go-fast somewhat stock engine.
This is the carb that (according to legend) Winfield developed for Master, then went on to build a very similar one on his own. NOTHING runs better.
This is a very nice example. 100% totally original. It will be spiffed more before shipping but it does not have and doesn't need any major repairs.
The photos show a hole in the top of the cover plate that I will thread and put a plug in. I will also dress the original needle and seat and test run it and it will be good to go.
In most of these the fuel rail has been messed with by poking wires and etc through the holes to try to clean the passages or they have been drilled with more holes or something. This is the nicest one I have ever seen and the fuel rail is totally original.
It is the "A" Master, which makes it the small one for Model T engines and other engines of similar size. The throttle bore is 1.125, the flange center to center is 2.1875 but one of the holes is slightly elongated so the mounting could be fudged a bit if necessary.
It is serial number 214.
It is ALL bronze with the exception of the screws on the arms, etc., which are steel, and the throttle barrel, which is Aluminum. That is one advantage of these over the Winfield and some other racing carbs of the same vintage, many of them are either made of pot metal or have pot metal parts.

Guess it didn't all copy from the other page.
$1000 including shipping in the US.
Couple things to mention.
One is that the mixture is adjustable from the seat with the cable connection shown. There is no choke as we think of it, you move the mixture control to full rich until it starts and then adjust it.
Two. It WILL drip a little fuel when you shut it off. Not a lot but the fuel rail will have a little drip.
Awesomely nice Carb!!
