I went to clean out the carb because it was running real bad at 1/4 throttle and when I put it back on and turned on the gas, it started dripping fast out of the black hose towards the bottom. So I took the carb off again and checked the floats and everything looked OK. Put it back on again, turned on the gas, and the same thing happened !! I didn't adjust anything when I had the carb opened, just blew out the jets and put everthing back together. Anyone have any suggestions ?????
