Hello Guys, This is my first time posting here but I've read tons of posts here before and after purchasing my Old Country Wrangler. I've had it for a little over a month now and I've done several test cooks. This weekend I smoked a 14 lb brisket and a pork butt. It was an 11 hour cook at 225 (actually 215-235). My problem is that I can't get the temperature to stay. So lets say that I want the temp to actually be around 225. It will get to 225 then creep up to 226 and before long it's at 235. I can close the damper a little and it will creep down and then be below 215. Even if I just open or close the damper a hair it will end up outside of my range. I can barely leave it alone for 10 minutes. This really sucks if you are doing an 11 hour cook. I've watched several videos and read posts but I can't seem to find the answer. Can you guys help me? I'm really tired! Thanks!
