Oh... You need some drip tips. Don't tell me you're using that silly little plug in the end of the cartomizer!!! EEEEkkk..
Get some 510 sized drip tips. They even have them in aluminum. Take that plug out and stick a drip tip in. Then you won't even have to pull it out to top off your carto (you ARE topping off your carto, aren't you??). A good cheap place to get them is ecigcharlotte.com because they have a good selection, they're only a couple bucks and shipping is only $1.99.
