The way I've been wicking this is to have a long piece of cotton rolled, just like I would wick a micro coil. Then I place one end down the side between the coil and chimney, and down to the juice channel. I pack it in there with the end of a small slot screwdriver. I then work the length of cotton around the outside of the coil to the other juice channel and pack that side. I continue to move the length of cotton around the coil until the cotton is even with the top of the coil (see picture above). Again, I look down the center of the coil and ensure that nothing is in there and I can completely see the airflow hole. Another way to accomplish this would be to keep a small phillips head screw driver sticking down the center of the coil, while wicking, to keep anything from getting in the way of the air hole. Also, when I say pack the cotton, I am packing it just a little tighter than normal; not packed so tight it stops the juice from wicking. Again, I hope this helps.
