MARVEL SCHEBLER Carburetor

Marvel schebler isn´t an exotic carburetor...they where common in aircrafts and staionary/industrial.
And they took something they had in their OEM line and then adapted it to fit as aftermarket for anything in demand.
 
I have now tested the carburetor extensively. The performance is better than with my two Ford 91-99 carburetors I own. In the lower speed range, my Ford Deluxe now accelerates better than before. And in the upper speed range, the engine now has a real boost. The acceleration to top speed has gotten much better. I'm excited. I can't say much about consumption yet. I haven't had to fill up yet.

Now I have made an consumption test over 300 kilometers (186 miles) with nearly constant 62mph (100km/h) on a German autobahn.
The motor took 15 liters per 100km.
This is really good.

That's about 15.7 US mpg.
or 18.8 UK mpg.

That's ok, isn't it, at constant 100km/h.

What vehicle is it? What gears and tyre size?
 
Is this the same Marvel carb.

A lot of the helicopters and other general aviation aircraft have Marvel Schebler carbs. They supplied a lot of forklift and tractor manufacturers as well. Manufacturing replacement carbs for those where patent rights had run their coarse was not uncommon. They made a lot of carburetors. Marvel Schebler Aircraft Carburetors, LLC is still in production under the Tempest Banner. Aircraft engines are about the only large engines still able to use a carburetor now days.
 
Just for comparison, I did a road trip in my '51 Ford a couple of years ago. It was about 160 miles round trip, with almost all of it freeway. Since this seemed a good time to check the mileage on my new engine, I filled up when I left and when I got back. Using the odometer reading and the gallonage from the last fillup. I came up with a figure of 19 mpg.

THis car has an otherwise stock 255 Merc with modified (optimized qurench) Edmunds heads, a Mallory dual point, and a 2G carb on an optimized Merc manifold. The car also has 3.55 rear gears, 2.25R15 rear tires, and no overdrive.

I believe the odometer in the car may be a little optimistic given the size of the rear tires and original speedometer gear, but it's probably pretty close.
 
I have a Schebler all brass carburetor for a 1926-27JD D tractor (yes JD made more than corn head grease). I think in 1928 Marvel was added to the name.
