The ideal fuel:air mixture is 14.7:1, by weight, not volume. Therefore, it takes nearly 15 pounds of air to burn one pound of gasoline. Since atmospheric pressure at sea level is 14.7 lb./sq. in., and the atmosphere peters out at about 100,000 feet altitude, it takes a one square inch column of air 100,000 feet tall to burn one pound of gasoline. Gas weighs a little over 6 pounds per gallon, so it takes a 100,000 foot column of air about 3 1/2 inches square for every gallon of gas! A clean air filter is essential, and it doesn't really matter if it's a paper pack or an oil bath, as long as it's free-flowing. I've got a stash of Rochester B's that are mostly junk. I'll see what the main jet thread diameter and pitch is, and compare it to some Holley jets I've got stashed away from my racing days. I don't think they will interchange, but it's possible something could be fabricated to adapt them temporarily. Holley jets are cheap! If so, the Holley jets could be used to tinker with the mixture, and the correct diameter Rochester jet could be selected once you're satisfied with the performance. Just an off the wall idea- - - -it might be totally impractical.
