is Blowin Smoke!
i have a 18 and a 22, niether need any gaskets or whatever, your going to chase temps in any cooker if you want one temp and the cooker wants another, dont snuff the fire too much have a nice clean burning fire, top vent open, unless really windy, get it going and close all 3 the same- only do this once dont chase it. So go like half way the next time on all 3 to see what it does go about half or 1/3 open and leave it there. i also prefer water in it but many dont.
