<P>What would happen if under those conditions, one were to spray the fuel lines, possibly the float bowls, with a product like Dust Off? It's basically compressed air, but gets very cold when used. I'm guessing it's a bad idea because of the temperature differentials and what it might do to the metal parts subjected to such extremes, but I'm just guessing. </P>
