I hope I have found the answer. Haven't tried it yet, but I'm going to. I found the following at an ATV answer site. The seat fits into the body of the carb over the fuel inlet port. The seat has an 'o' ring that holds it in snug. Fuel seeps past the seat 'o' ring where it sits in the fuel inlet. Chang the 'o' ring and it should stop the leak.

possibly the needle valve in the carb if the gas stops running out when the engine is running that's my bet

i may be too late, but this happened to me a while back. The drain plug of the carb bowl has a rubber support under it. i have no idea why, but the rubber contacting the steel rubbed a hole right through the center of the drain plug. this caused gas to leak when the engine was stopped and made the motor run rough. it was a cheap part, but took two weeks to show up...easy fix though.
