Ok I have an 84 atc125 that when I got it out hadn't been started or even attempted to be started in years. I've since pulled the carb & cleaned it enough to where it'll start & stay running. However heres the problem, when it's running gas pours out of two small overflow hoses (least I think thats what they are) any idea why this is happening?

 

Sounds like your float is stuck, it is not rising to shut off the gas as the bowl fills up. Need to remove the bowl, free up the stuck float, and make sure it is set to the right level. Check the seat on top of the inside of the bowl, and the actuator that contacts it from the float for any dirt that would hold it open.
