oldwhizzer ....................... How about taking some photos, out in the sunlight, so we can see more details. That's the oddest "A" carburetor that I have ever seen ! I sure don't know what it is. MIKE
It is probably that carburetor that got 55 miles per gallon that caused the oil companies to place a hit on the hapless inventor! It is a carb & air filter combo.
Man, that is a really odd carb. I think it belongs on this odd Model A intake manifold.
The louvers act as a silencer and as an air cleaner. The air is spun around as it enters, and throws the dirt to the outside where it falls to the bottom. The bottom is easily removed to dump the accumulated dirt by just spinning the thumbscrew loose and swinging the bail wire to the side.
It looks like a possile experimental Holly carb. On forever4 website in Jan of 05 there are photos of a simular design, the only difference is the slotted cover on the bottom held on by a bale.
It's not mine. I saw it at the Kansas City national meet about 10 years ago. It was found at a farm auction about 50 miles north of me near North Branch, MN.
It would be nice if the owner installed it and did some dyno tests.
