Leaking from carb overflow only on number 2

Easy I thought, the bikes been stood a while, so I removed carbs, cleaned the float valve.
Put some new fuel lines and fitted in line filters and I thought that would be the end of it. Nope still leaks only a few drips a minute but it bugs me.
Ok, plan B. Ordered a carb overhaul kit and fitted the new valve and seat. Just put it back together, guess what no difference..........
Any ideas/advice appreciated, I must be missing something.
Cheers
Its a 1000 a1

Make a manomter to check fuel height from piece of clear tube,put float in petrol see if it leaks,ie sits lower than the others

Swap float bowls to see if the fault moves

just twist the brass tube with some pliers & it should come out
