I've heard of classic cars stinking like fuel from the carbs park in a garage after being run on the road...

Is the same thing happening here? After a fun day, park it with fuel cutoffs OFF. I just re-did my reeds with stuffers and noticed my Prok flame arestors have a few drops of fuel/oil mix on/in them, and also on the inside rim of the flame arrestor adaptors. I also notice some fuel/oil mix is dripping into the hull. I dont think its much or enough to start a fire, but its enough to make my garage stinky. I didnt notice this before rebuild and with the stock airbox - but inside the stock airbox there was the same thing - fuel vapor/drip.

The source is coming from within and inside all three carbs. Are my freshly rebuilt carbs leaking or is a little fuel drip vapor somewhat normal?
