The Miller Master Carburetor for the Model T Ford

Harry Miller’s factory at 6233 South Gramercy Place in Los Angeles, CA about 1926.

Harry Miller was many things. Perfectionist, engineer, designer, effete, driven, winner, dominating force, all could be used to accurately describe Miller and his products.  Miller racing engines won Indianapolis and most any other race that mattered in the 1920’s. His engine designs came to be used in later years under the Drake and Offenhauser names, dominating Indianapolis through the mid 1960’s. r race that mattered in the 1920’s. Miller designed aircraft engines, boat engines, fire trucks, and of course carburetors. All were (for the most part) successful and profitable.  This week we take a look at the rebuilding, installation, and performance potential of the Miller Master carburetor on the Model T Ford.

Installing a Winfield Updraft Carburetor on your Model T Ford

The man himself – Ed Winfield. A large Winfield carburetor can be seen in the hood cutout. This racer featured one of Ed’s infamous “Two up – two down” Model T Ford engines with a crankshaft, camshaft, cylinder head, intake and exhaust all designed and built by the master of speed. Photo from about 1928. 

We have long been fans of Winfield carburetors for Model T Fords. There were many designs offered by Winfield over the years. Some are updraft, some down draft, some side draft. In this article we focus on installing an up draft Winfield designed for improved T performance.

Rebuilding the Kingston 5 Ball Carburetor for your Model T Ford

Kingston sold hundreds of thousands of five ball carburetors to all sorts of manufacturers. They were used on everything from tractors to motorcycles, boats, and stationary engines of all sizes. The carburetor in this illustration has a threaded inlet, so it is not for a Model T Ford.

The earliest Model T Fords used the Kingston 5 Ball Carburetor. By all accounts the performance was and is great with the Kingston 5 Ball.   A few Model T’s in 1909 also were produced using another type of carburetor made by Buffalo, but those carburetors are seldom seen today, and Ford did not use many.  The Kingston 5 Ball is a very simple and sturdy all brass / bronze design. The five balls provide a secondary, on – demand air supply for the carburetor. As engine speed increases the decreased air pressure above the balls causes them to lift off their seats as needed by engine demand. One, some, or all of the balls might lift depending on airflow. This makes the carburetor very efficient and helps to eliminate flat spots with various throttle openings. Read on and we will see how to rebuild this carburetor.

Rebuilding the Holley NH Carburetor for your Model T Ford

The most common of all Model T carburetors is the Holley NH. It was first used in the 1920 model year, the primary carburetor supplied for all Model T Fords and TT fords. This advertisement shows the earliest version used by Ford which has a so – called “straight thru” venturi throat arrangement. It also uses the earlier style float bowl with side drain.
  

In this issue we will examine the simplest (and some say best) carburetor ever used on the Model T Ford. The Holley NH was introduced around 1916 as an accessory for the Model T, sold by Holley along with a special intake manifold. Eventually the NH replaced the earlier Holley Model G in regular production some time in 1920. Read on to see what a typical overhaul of one of these carburetors entails.

Replacing the Exhaust Manifold Glands and Exhaust Pipe on your Model T Ford

In our most recent tech article we rebuilt the muffler. After the new muffler was in place we were able to enjoy a much quieter T driving experience. But now we could hear exhaust leaks under the hood. Clearly a more exhaustive examination was in order.  In this issue we will show how to make this common job easier and how to get great results every time.

A 3Z624 Ford Exhaust Nut wrench was used to remove the exhaust pipe from the manifold. If you own a Model T you need one of these. Reproductions are sold by all the Model T part vendors. There is no way to properly tighten a T exhaust nut without one.
