Weird carbs on ebag...
So far this is the only thing I have found on the Woodworth carbs. It's bugging the hell out of me that I can't find any real good info on these things. I don't know why Im hung up on this but I figure what the hell I don't have anything better to do.
1. Its a bold company that spends nearly eight years improving a
product that may not be around 20 years from now. But thats
what the Vacuum Carburetor Corp. of san Antonio, Texas, has
done. The firm has developed a new vacuum-controlled
constant-velocity carburetor, better known as the Econo Carb,
which its maker says offers several advantages over ordinary
carburetors including 25 per cant better gasoline mileage,
improved engine performance and easier starting. The device
which has only 54 parts compared with some 300 in regular
carburetors, has no choke or accelerator pump and therefore
cannot flood. The device constantly adjusts the mix of fuel and
air in the manifold, which regular carburetors with fixed mixes
cannot do. When your engine demands fuel, it will give it just enough to do the job, says Frank Greene, president of Vacuum
Carburetor. Its the same concept as a cruise control.
2. The vacuum carburetor is not a new idea some of the earliest
carburetors (in the 1920s and 1930s) were vacuum-type. Al
Woodworth, Californian, invented a modern vacuum carburetor
several years ago; what Vacuum Carburetor has done is modify
Woodworths creation, mainly by adding a fuel-injection coldstart
mechanism that, the company claims, helps the engine turn
over immediately in frigid weather.
3. Though the Econo Carb has been on sale for less than a year, its
already being used by municipal car, truck and cab fleets in
Nashville, Denver and San Antonio. Whats more, Saudi Arabia,
China and Denmark are interested in importing the device.
William Moreton, an executive at Vacuum Carburetors
production plant in Kansas, says the Econo carbs natural market
is as a replacement for existing carburetors, especially in V-6 and V-8 engines.
