Gas is dripping out of the vent tube that hangs out the bottom of the skid plate. I put gas in the tank and it drips out of the tube until it is empty. What would cause this to happen?

You don't say what machine you have but sounds like you have a float needle valve or seat leaking. Pretty common issue. You should always turn the fuel shutoff valve to the side/"off" position anytime the machine will be sitting a while. On some carbs the needle seat has an o ring under it that deteriorates causing the leak. Other times its the needle valve itself allowing fuel to leak past it because of dirt, gum or deterioration.
