I picked up a VN the other day and the little air holes above the 510 threads don't seem to let any air in. With the tank off of my battery, I press my finger up on the battery pin to seal it off. The 2 air holes are unobstructed. No air flow at all. I've seen elsewhere on the forum that there is a fix for a tight draw, but this seems to be no draw at all. Am I crazy? Shouldn't there be air coming through the air holes even with my finger over the battery pin area?
