the retaining nut contains the transfer passage or metering jet through which fuel is delivered to the high speed AND idle circuit of the carburetor. If the problem occurs with the idle circuit examine the annular groove in the retaining nut. the passage must be clean for the proper transfer of fuel into the idle metering circuit. torque retaining nut to 50 in lbs when reinstalling. there are two types of nuts used on float style carburetors. One has two fuel inlet ports and the other has a fuel metering port (both at the bottom of the nut) the idle fuel transfer passage is at the top of the nut. That being said I still think your description sounds like float sticking due to fuel deposits or when the fuel tank is filled for the first time.
