i'v been having an issue with my smoker running hot. I'm on my third smoke, i filled the bowl with water, i closed all the vents. I have a pit master iq attached with a maverick thermometer. I put one chimney full of unlit charcoal, and put one chimney of lit charcoal on top, i'm wondering if maybe i'v put to much charcoal? i'm trying to get the smoker down in the 220 range and it wants to be in the 300's. Any help would be wonderful.
