    Hey Susan,
            When a gas tank isn't full, the space above the gas, water vapor,
    tends to condense as the temperature changes. This, of course, drips down
    into the gas and goes to the bottom of the tank. So you start the engine
    and all is well untill you start moving and the gas/water gets all mixed
    up and sucked into the motor. Whammo! The trick is to keep your tank
    either full or empty when you're not going to use it for a while. If it's
    just a small amount of gas just dump it out. If it's a large amount or
    dumping isn't practical, add a gas dry product. This is basically alcohol
    which mixes with the water then mixes with the gas allowing it to burn.
            Whew! More about this than I'm sure you wanted to know ;^)
