but your the expert buddy
That's what i'd guess.
Your carb belches gas back up into the air filter. It leaks down and pools up in the carb box, and then drips out the back down the hole in the back of the carb box.
Now, there's actually a rubber plug to fill that hole, which would probably stop the leaking down the back.
