Diagnosis? Fuel leaking out of Dellorto air trumpet

Hi Gents
My daily driven and occasionally tracked Plus 2 S has fuel leaking out of the rear air intake trumpet on the Dellorto. This happens while parked with engine off and leaves a fuel puddle on the ground so it's quite a big leak.
It's almost certainly related to a driving fault I've noticed. When parked hot or idling at lights, the engine tends to flood (I think only the rear cylinder). A few blips of the throttle pushes out some black smoke and then it runs in tune (not rich).
What's happening to my rear carb while parked and at idle? Diagnosis much appreciated.
Many thanks
Simon
