To anyone having wicking issues. If you are using thicker juices and are not wicking fast enough. Make sure the tank is mostly full and vape with the fill screw removed. This should help you wick faster and get you blowing big thick clouds of vapor. Also make sure that you are not using too few coils. Thicker juice can burn quickly because the slower flow so you want to have 4 or 5 coils instead of 3.
Also, oxidize the wicks from top to bottom, this definitely increases flow.
When you are breaking it in, you can burn it for a while with the top tipped down and the cap off. If you get the coil good and hot you will son see that the liquid will just start to pour right down the wick and out the top of the wick. Once you see that, the wick should start flowing very nicely and be sure that when you go to tape that the top cap is on securely and sealing at the bottom of the top cap. If not then the airflow over the coil will not be as strong and you will get weak/burnt hits.
Hope this helps.
Let me know if this does not take care of the wicking issue.
