I thought some of you here who own a Sunderman carb might enjoy having a copy of the original instruction manual to go with it.
Jay I have one of those carbs just never did find the sq intake to mate up with it.

Wow! Saves 50% of your gasoline! No wonder they are so hard to find. I'll bet the oil companies bought them all up. Of course, my uncle's neighbor's father bought a car with one of those. It was an experimental model that somehow got out of the lab and onto a production vehicle. No matter how far he drove it, he always arrived with more gas than he left with. Eventually, he started having to syphon off gas from the tank to keep it from overflowing. Then one night, some guys from the oil company came and........
Be honest. You know somebody that has told this story, don't you? I do. Where ever that boy is right now, I promise you he's telling a lie.
Ah come on now Hal - That sounds like a 'Fish' story . . .
Yeah, back in the 50's someone built a carburetor that would give 100 miles per gallon. Last I heard, Standard Oil bought the patent. Too bad no one else has ever figured out how to do it.......
Chuck, yep, I've heard that story since I was 10 or 11 years old(I'm 64 now). The brand of car and the circumstances of how it came to be and how it was removed and who removed it usually vary, but it's basically the same story. There is a retired banker(no dummy by any means) that lives here and he still believes it. So far, I haven't heard one about fuel injection units yet, maybe we ought to start one<g>. Dave
I really shouldn't have hijacked Jay's thread (That IS a really neat carb!), but that claim of saving 50% of your gas was just too much to resist.
On a similar note, I heard a story once about some guy who had converted his pickup to run on propane or CNG or some such where he no longer needed the fuel tank. He stopped off at a gas station and decided to have a little fun with the attendant. He went inside and bought a tin of aspirin and asked if he could use the water hose. He goes out and puts the water hose into the fuel tank and proceeds to fill it up, then makes a big show out of taking a couple of the aspirin out of the tin and tossing them into the fuel tank. Then he supposedly gets in the truck and drives off. I have no idea whether this was true, but it made for a funny story either way.
Would you have an instruction booklet for the Marvel carburetor?
It is not unrealistic to say that they would improve the fuel mileage by 50%. Not under all conditions but ..............
Before you make too much fun of them, they were one of the first successful air valve carburetors for Model T's. They were first on the market in 1915/16 and were a massive improvement over the Kingston L-2, which is what was being supplied on Fords at the time. The concept of the air valve operating the fuel regulation needle at all times was not a new idea for carburetion but was applied here to a small carburetor for smaller engines, such as a Ford. Notice that there is no connection to the standard Ford adjustment needle. Once adjusted, the fuel regulation is by the variable vane in the inlet. Most of the wasted fuel and fuel problems with other carbs was the failure of proper adjustment by the operator. By running a quite lean mixture at initial setting the Sunderman not only decreased the amount of fuel used at low power requirements but also greatly decreased the possibility of fouled plugs, which require more fuel to ignite the mixture.
They are great little carburetors, were on the market for about 10 years with virtually no changes, thousands and thousands were sold and there are still a lot of them around. You would be amazed at how well they run. I have a new old stock one that I bought at the Lethbridge swap meet.
The square design is pretty smart, too. Is is far easier to make an air valve that opens and graduated amount if the hole and the valve are the same square shape. It's also cheaper. Think about it.
I ran the Sunderman carb on my '13 for a while. It is a very good running carburetor. I used it with the standard '13 aluminum intake. I took it off mainly because cork floats make me nervous.
Sunderman sold this intake separately from the carburetor. Notice how low it places the carburetor, I wonder if that was to give a little bit better fuel pressure?
Thanks Stan. I'm not real concerned about improving my mileage, but I have to say your description makes it intriguing. What do they usually go for, if you were to find one at a swap meet.
I paid $75 for a new old stock Sunderman at Chickasha.
