The power valve is a vacuum operated valve that adds a little extra fuel to the carb jetting for more power when the engine pulls hard. The problem is that this valve has a rubber diaphram that has gasoline from the fuel bowl on one side,and a vacuum passage to the intake manifold on the other side. If this diaphram gets a hole in it,then gas from the fuel bowl will run through the hole and directly into the intake manifold,causing warm flooding and an empty carb if parked overnight.
If you see gas on top of the intake manifold,there is a good chance that the rubber accelerator pump diaphram has a hole,or the pump cover is warped allowing gas to leak out of the fuel bowl and on top of the engine. Either problem will drain the carb in a few hours.
