Too much fuel?

Guys, yall all know with ethanol in the fuel, it's damn near impossible to read plugs. So if his plugs are black, it is 100% a fuel problem. Could the timing be affecting it too? Sure, but not so much to turn the plugs black with ethanol laced gas. Ain't happenin. Sounds to me like either the floats are compromised and taking on gas, or there is dirt in the needle and seat holding it open. Either way, you have a CARBURETOR problem.
