Getting frusterated with the temp in this thing I am smoking two racks of baby backs for dinner tonight I put them on at 1:15 and the tewmp was around 240. An hour later it was staying at 200 and after about an hour and a half I couldnt get it to raise above 212. My coals kept ashing over and choked it out. So I took everything off and put a fresh chimney in using the minion method, my temp is not raising to 240 its just kind of sitting there under 200 I have no idea what to do at this point, am I screwed on this batch or can I save them?
