So, second smoke on the ECB. Prime rib ribs and some pork side ribs. Really strugg getting the temperature low enough. Built a minion fire (after drilling a bunch of air holes as per the suggested mods). 20 minutes into the smoke i had temps over 300! So removed the top of the smoker and toom out about half the coals. Still have to have the lid cocked and the door open just to get down to 240 ish. i'm an hour and a half into my 3 2 1 and have a huge pile of hot coals laying on the concrete beside the smoker and stil can't get it cool enough. Help?
