Went to start my 450 today and when I turned on the gas the gas was leaking from the tube coming down the right side of the carb(if u r sitting on it) it is not the float tube it is the other one. The gas was pouring out. I drained the gas out of the carb the dealer said it might be the pin valve in the carb or just gunked up. I havent tried it since emting the gas out of carb because battery is recharging another dealer i spoke to said the float could be stuck and to tap on it, any suggestions it would help. I havent started it since the last time i went riding about 3 weeks ago so i think this has to do with it. thanks
