57, where did the fuel in the carb bowl go? possible engine damage?

After getting my carburetor rebuilt, I decided to let the fuel drain out of the bowls for long term storage as I fix the rest of the car. I unscrewed the fuel bowl bolts to do this, but there was no fuel in the primary fuel bowl. The secondary bowl drained fine.

What happened to it? I have heard that if fuel leaks into the engine, it could fill the cylinders, and cause catastrophic failure upon the next attempt to start the car(flooded?/seized? engine?). Is this something I have to worry about?

The amount of fuel in the primary bowl is not enough to cause the engine any damage on the next start.
If you are concerned, pull your plugs and turn the engine over by hand
