I need information on this Master carb

[elliott1936]

I have a rebuilt brass Master up draft carb that I would like to know where it as used and years that it was used. Any information would be helpful.
I would also like to what it is worth. If someone can use it, also let me know. Tom Elliott five03-644-937Four

That is an early Miller Master carburetor rare and expensive.

The article written by Royce Peterson gives a great overview on these carburetors. Lots of very useful information.

The Miller Master carburetors are probably the best carburetor you can use on an early car. These carburetors have very few parts and everything is either machined brass/bronze or steel. No die cast, no aluminum, no cork and no gaskets. These are precision devices yet extremely simple by design.

The Miller Master carburetors came in a variety of sizes. Shown here are three with 1 1/4", 1 1/2" and 1 3/4" bores. There are external casting variations but the interior parts are basically the same.

The bore size usually determines its application. 1 1/4" inch would be good for a lightly modified Model T. The 1 1/2" might be good for a "racier" engine and the 1 3/4" would be for an engine with a a much bigger CID than a Model T. On a T speedster, I am running a Rajo C-35 head on a stock T engine with a distributor and a 1 1/4" Miller Master carburetor. It runs REALLY well. Outperforms a similar size barrel-valve Winfield by a long shot and much better than any other aftermarket carburetor I have tried.

Your carburetor looks to be a smaller size version- I am guessing 1" to 1 1/4" bore, which would be suitable for a Model T or a car with a similar size engine. Your example as shown looks great but is missing the air intake assembly. I think it would be almost impossible to find one that isn't already attached to a carburetor.

I have one that Stan rebuilt. Have yet to run it.

If anyone can direct me to a source to locate the missing intake throat to this carb, I would be very happy. The carb has a 1" throat size. to the outlet of the carb, Manifold intake size, If that will help. I have a picture of the intake area. This is the intake and choke area I think. I hope this will help. It looks like the intake housing has different looks. I will take what ever I can get.

They are a beautiful piece of craftsmanship and automobilia, too . I picked up a NOS one awhile back at an Amish antique shop, of all places. It was a bit too big for a T, so it went down the road.

Tom, that smaller inlet is the idle air inlet, while the larger opening feeds air once the barrel starts to uncover more and more holes on the jet bar.

Take a look here and steal the photos...it shows exactly what your inlet should look like...don't worry about its larger throat...you are interested in the outline and details of the inlet: https://mtfca.com/phpBB3/viewtopic.php?t=3218

an elbow and hot air pipe attached to the idle port opening:
