It's a over flow hole so the gas don't swamp the crankcase. When this happens it means the float is stuck and the fuel inlet valve is staying open or the float has a pin hole in it and it's full of gas and can no longer float to close the fuel inlet valve.
Quick fix, start the engine and tap on the side of the bowl with a pair of pliers and if the gas stops running out of the over flow then the float was stuck. If not pick your code date from above and rebuild it.
