already did that still happening then it seems like its running out of fuel but still overflowing it was doing same thing with single carb set up also could it be something with the vacum line
Verify that the Needle vales are actually closing and stopping fuel flow.
If they are not sealing when closed it will either flood the engine or pour out the overflows/vents.
