Found some matches.
Just a guess, are you opening the lid a bunch?
No, trying to avoid it. Put coals in, closed lid, waited 15 minutes. Put in ribs, let it go. Temp started at 235 and climbed up past 330 within about an hour. Tapped the vent closed a couple of times, but continued to climb. Sitting at 360 now, but I'd guess part of that is from the air coming in when I pulled the ribs.
I'm not terribly worried about the actual temperature level, I know this runs hot. But the fact that it never settled is making me wonder if I've got something set up wrong.
