altho actually rare,...leaf valve problems do occur,...if u have a lot of fuel spray coming back,ck it out,...u WILL get a slight mist,just fr norml operation,and ur prob would lie elsewhere...float level ,sticking needle,..etc,etc...

With the engine off, look down the throat & pump the primer bulb. See if you can see the carb overflowing in the bore. (Float/seat/needle issue)
