Yes, I realize that. The previous owner did NOT have it blocked off and when I parked it in my garage there was a half dollar sized gas puddle underneath the nipple. MY question is, is gas supposed to drip out of that hole when it isn't plugged up. I'm not too knowledgeable on carbs so that's why I ask. I just want to make sure there is nothing internally wrong with the carb. And I need to know what size jet for just an airbox lid off and a uni filter.
