The typical effects of today’s gas and too hot of an intake manifold.
Today’s fuel boils off at 150 degrees.
Do you shut the motor off the carb(s) heat soak, the fuel not only expands and raises the fuel level but slowly floods out the carb.
And this is not to mention the fuel vapor side issue .

Your return line releaves the pressure of hot fuel expansion.
