Hi all, I've had the 22" Master Touch for about a year now. When I first got it, the cleaning system was replace under warranty because of excessive gaps, not even touching the bottom of the bowl. The replacement fit better, but, still isn't near as flush as on my old 18". I'm currently smoking some beef short ribs, and having a heck of a time keeping the grate temps below 300 degrees, running a 2x1 snake. The bottom damper is completely closed off, and top damper barely 1/4 open. I feel I am still getting way too much airflow. This kettle has never been able to choke out the coals like my 18" does with all vents fully closed. It feels to me like the cleaning system needs a washer between the bottom of the bowl and the handle, as there is about 3/16" of vertical play, where I can puch down in the center, and the blades make good contact. Does anyone know of a washer available that would fit there? I thought about buying a fender washer, and drilling a hole large enough to fit, but, clamping the washer securely during drilling seems sketchy at best.
