If you have replaced both the gasket at the top of the bowl, and the gasket under the nut holding the bowl on, there are two more things to try. First, shut the fuel off and unscrew the brass adjusting screw that is centered in the nut which holds the bowl on. You will find an o-ring on this piece - replace the o-ring, being careful to note in which groove the old o-ring rests. Put a little grease on it and put it back, bottoming the screw, then opening it back about 2 1/2 turns. It's purpose is as an auxilliary source of fuel, in addition to the fixed jets in the carb. While you have the piece removed, on the end of it you should find a small, tapered piece which can be moved around. If all you find is a pin, the tapered piece is stuck in the neck of the carb and needs to be removed. You will need to get a new adjusting screw if that is the case. Finally, if that doesn't solve the problem, contact Robert's Carburetor Repair www.robertscarbrepair.com and get a couple of the soft gaskets he sells - put one on each side of the hole through the bowl and replace the nut. You might also get a new gasket for the top of the bowl as his are soft and work better on old surfaces. The fuel level in the duplex carb is right near the top of the bowl, so sealing there is critical.
