carter afb: fuel disappears?

As I've said in the other threads, I believe that the ~1/8" plate is the better bet for combating fuel bowl boiling while under way. On a hot shut-down I don't think that there is much that you can do. The plate will shield the AFB bowls from heat radiating up off the engine and that may buy you enough time for the engine to cool before all of the fuel is boiled off.
