thank you patrick for showing us how much you know.

the adjustment for a pump shot is at WOT. for a stumble


but to get back to the problem of fuel dribbling at shut off the pump lever should not be in contact with the pin on the pump. to adjust that at WOT will not help this.

some slop .010-.015 at idle should be there or the off idle circuit will be sending fuel to the venturies and cause a dribble. you can hear it dribbling sometimes in the exhaust at idle....a little fluctuation in tone
