Leaking Fuel, Won’t Start

[Roscoe]

Sounds like it might be a couple of problems, Your scooter must have a fuel petcock if it's dripping that much gas and that should have shut the gas off, and the needle and seat in the carburator should also seal and stop gas from running out.... make it three problems, the fuel filter/screen and a clean gas tank with good clean fuel, those have to be in good shape to keep debris from causing the fuel petcock and needle and seat in the carb from doing what they are supposed to do.
