Is that related to (or the same thing as) that situation where, on a cold morning, if you step on the gas you get that hesitation before the acceleration? That happened occasionally on my gasser.Ok I won't use the term supercooling. Ice can form on bridges even when the outside temp is above 32F. This is due to air flow under the bridge and pressure drops that can occur (change in pressure = change in temperature).
A good example of this is on my 70 air cooled VW beetle intake manifold. Even when it is 80 degrees outside, the pressure drop causes temps to lower and gas to drop out of suspension in the air. Also deemed a "frozen intake" they can get down to 40-50 degrees in the summer which is why tubes were put in later models to pull off exhaust gas and run it through tubes welded to the intake. This helped keep them warm and prevent the gas from "freezing".
