In The Fish Carburetor Book by Michael H. Brown you will learn all about the Fish carb with only three moving parts (see Books).
From 1947 to 1959 the Fish Carburetor Company of Daytona Beach, Florida manufactured over 125,000 high-mileage carburetors. The Fish carburetor averaged 20 percent better gas mileage and 30% more horsepower. The Fish carb would also run on a variety of fuels with no internal modifications, from farmers’ alcohol to paint thinner and parts cleaner.
The Brown Carburetor Company of Draper, Utah manufactured almost 10,000 new Fish-design carburetors from 1981 to 1996. This book was their manual.
The last chapter contains, among other information, how to get a 50% increase in power and mileage with a piston and camshaft arrangement. It is this piston and camshaft arrangement that gave rise to the “urban legend” of the superior carburetor. It wasn’t a carburetor. It wasn’t a legend either.
