Hey guys, I am fairly new to the world of smoking meat and recently got a Oklahoma Joe’s 3 in 1 combo smoker/grill. During my first trial run controlling the temp I struggled quite a bit. I have been learning of the different mods people do to their offsets and since have added gaskets and tuning plates which has made a huge difference. On this particular smoker there is a hole at the bottom of the smoke chamber joining the gas side of the grill. My question is, should this hole be plugged? To me, it seems this would let a lot of air in since there are vents on the gas side of the grill. I haven’t seen any threads that touched on this. I have thought about stuffing it with fire blanket to plug the hole but I am not sure if it is there for a reason that I'm not seeing. If anyone has any experience with this grill and what they’ve done with this hole, if anything, please share.
