Some have a primer, some do not. I only have experience with Joyetech attys and they do have primer in them.
Before I use a new atty, I blow the primer out. To do this, loosely cover the open end with a paper towel and blow through the threaded end. I blow as hard as I can a couple times. Then, roll up a corner of the paper towel and dab the excess primer out of the open end of the atty. Next, blow through the threaded end a couple more times and dab again with a new corner of the paper towel.
After blowing out the primer the atty should be ready to use. When dripping, I use a 510 to 510 sealed adapter and a drip shield. This helps prevent juice from leaking all over the place, if/when you over drip. If you are using a bridgeless atty, drip 4-6 drops of e-juice. Bridged attys usually need 6-10 drops to start....
