Welcome to the world of Stromberg carbs.

Doubtful. But one way to test this is to turn the fuel off and pump the
primer
dry with the engine running and see if it persists. I bet it will.

The normal 'Stromberg drip' is from the float bowl running over due to the

needle
and seat not being able to hold back the pressure from the header tank. 
This one
sounds different, since you're saying the fuel valve is closed. Where 
exactly is
the drip coming from?
