Same issue here on my K1. Leaking from overflow tube. Tried adjusting, but never stopped until I replaced the needle and seat. Runs great now. Earlier in frustration I blocked the overflow tube and the airbox would have fuel in it. That's when I didn't need the choke to start it. Cost of carb parts so low.....just get a rebuild kit. Well worth it when you see the bike running again like new. Just went to garage and looked, my overflow tube comes off the bottom of the carb.  And I seem to remember there is a passage in the bowl to run the drain to the top of the bowl.
