I just got a 1986 Suzuki LT230s, and the problem is if you leave the gas turned on it will leak out of carb hose that goes from the bottom of the carb to the ground. Also, whenever it gets hot, the quad will start running bad like its missing and wont idle very well. I just replaced the spark plug today and it still does it. Can anyone help me out because Ive never really worked on carbs before. Thanks.
