Bought my son a used quad in great shape today its a 2000 yamaha warrior 350 off a friend who hasn't used it in 7 years . installed new battery today and took carb off cleaned it and put back on started right up ran fine until I shut it off it leaked a half a tank of fuel on my garage floor and my house stinks now . Lol..... it leaked out lower over flow hose that come out of the reservoir where the floats are . Wondering if the floats are stuck open ??? Should I rebuild The carb or is it something stupid ? There has to be someone on here with some experience ????
