Hey guys! New to smoking and new to the forum. I bought an old country wrangler smoker from academy last December. I have cooked maybe 10 times on it so far. I am having a hard time with the temps. I have a maverick digital thermometer on the grates. It's almost like its working backwards for me. When I close down on the firebox damper the temperature rise and when I open it they fall. I have the damper wide open on the stack as well. Can anyone explain this to me please. Thank you.
