Miller Master Carburetor … Alive

Post by Mark Osterman » Thu Aug 24, 2023 9:13 pm

Those who follow my personal facebook page know that I was was struggling to get a Miller Master Carburetor to run correctly a year ago. I had found it at Hershey and really wanted to see what it would do. They don’t work like other carburetors with a rotating drum for the throttle and a hollow brass piece with thirteen tiny pinhole jets called a fuel distributer. I discovered that four of the jets were clogged with solder so I disassembled it to open those jets. The second time I tried it I found it would only idle because there was a gasket leak I couldn’t see. With the kind assistance of Royce, who wrote a great article on his own experience with restoring a Master, he was able to confirm that my rebuilt fuel distributer was working as designed. I reinstalled the Master Carburetor several days ago and it is everything it’s designed to be. Amazingly slow idle and yet incredible acceleration with amazing hill climbing strength. I only know two people who have a Master carburetor in their cars. I would appreciate hearing from others. Here is a youtube video of the carburetor running at a fast idle. https://www.youtube.com/watch?v=4LDYKbrK2Vo

I have 2, a small and large one neither of which are ready for a car. I have been thinking about using the large on the "baby Chadwick" but first I need to fabricate some pieces using the small one for a pattern.

Could you please post a picture of the Master Carburetor installation on your model T. What letter is stamped on the end of the fuel distributer bar?

Hi Mark,
My Dad and I have one that has an “E” on it.
What is the significance of the letter designation?
