I set the floats spot on with a tube.
Left the bike for a couple of weeks (been super busy since I bought it) and it pissed fuel out of the overflow as soon as I turned the fuel on.
It has all new jets etc so I thought the float needle may have a rust flake or similar holding it open. I stripped off the carbs(again!) and found the brass float full of fuel. AH HA !!!
now I know why it keeps flooding.
Anyone got a spare brass float?
