Our floats are a hollow, hard plastic piece. It would be pretty difficult for a hole to form but it's not out of the question either.
When you cleaned the float valves and seats, did you check to see if the rubber end of the valve was deformed? This can cause it not to seat properly and therefore pass fuel. However, it has to be more than a stuck or leaking float valve because a flooding float bowl usually passes the fuel to the cylinder, not the air intake. If gas is coming out of the air filter, were the boots full of fuel when you pulled the carbs? It sounds like the air/fuel mix is not making it into the cylinder or a good part is not and is backing up into the intake. Maybe the slide assembly isn't working. Did you take the large diaphram covers off and check the diaphram for the affected cylinder? It may have holes in it which could explain your problem.
