I did get this sorted out. I dropped the bowls and checked the float valves and cleaned the seats with carb cleaner. Bowls were clean and everything looked good. Reassembled and still leaked, both sides actually. Now the carbs come off. I bought 2 carb kits and cleaned them spotless. I reassembled with the new parts and hooked a fuel line to them then added gas to see before mounting on bike. Not as bad but still leaking. Bowls come off again and I got some polish on a q-tip and polished those float seats then flushed them with carb cleaner. Try adding gas again and 1 side still leaked after a 3 hour wait. I took that side off again and polished the seat some more and that did the trick. I left the carbs sit with gas to them all night and not a drop. Put them back on the bike and no more leaky carbs. Since the float seats aren't replacable you really got to clean them. I hope this maybe can help others as I've seen from my searching it seems common for these older bikes.
