Out of boredom I was watching a build tutorial for the OBS engine and it was suggested that you should pull the coils up towards the top of the deck since it is a top air flow tank. So I opened mine up, pulled out the wicks and moved the coils up until the coils were almost even with the top of the deck. I rewicked, primed and refilled with my favorite flavor juice and let it sit for 10 minutes. I then hit the fire button, took a long pull and was amazed at how much more flavor there was. It is so logical, but I am so used to the air flow coming from the bottom of the deck that it never occurred to me to do the opposite for a top air flow tank. I have been enjoying massive flavor all day!
