4 bowl screws (either flathead or 5/16"), a 1" open end and a 5/8" open end for the fuel line going to the primary bowl, and the same 1" open end wrench to remove the power valve from the metering plate. You will need a new bowl gasket and a new metering plate gasket. Both have to be removed to get to the power valve. Make sure your replacement gaskets are BLUE, NON-STICK gaskets, and make absolutely sure that you clean off every single piece of old gasket material from the bowl, both sides of the metering plate, and the body. After you remove the power valve, look along the edge of the hex pattern, or on it's surface, for a number. Probably 65. Replace it with a power valve of the same value, and don't forget the power valve gasket.

Take care
