May I ask how the adjustable air draw works? Does it have to do with how much you close or screw down the cap? I seem to have a good sized gap between the bottom and the cover. My first build was airy and floody and second build hot , too much TH and dry/burning.
I had this issue at first...my cap wasn't actually seating all the way down...
I remembered that as with all super T products I've had that this is precisioned machined with tight tolerances...
What this translated to for me was that the threads and O-ring were stiff at first and once it was used a time or 2 and the condensed
juice got onto threads and O-ring and sort of lubricated things...suddenly the cap turned from stiff to that buttery smooth feel we're familiar with as far as super T threads go...and the top then did screw down and seal off airflow completely...
I think that not only will having something on the edge of the deck impeed the adjustable draw....but you have to make sure that the threads and oring are lubricated with
juice (or condensation) and broken in.. put the strata on your device and work the cap all on and off a few times...there will be a slight difference in feel when the ring is finally lubricated and seats...
