Hey folks! Recently purchased the Char-Griller Akorn 6520 (grey, with cart) at Home Depot for $329. I have really been struggling to control the temperatures with this guy. I've read numerous articles and threads that suggest the best way to start and maintain a low and slow fire (~225F) in the Akorn/Char-Griller kamados, but my temperature is either heading north of 300 or dying completely after an hour or so--I'm getting desperate. I'm using 100% oak lump charcoal with the firebox filled up about 3/4. I'm using between 1/2-1/4 of a Weber starter cube. I light it up, and wait about 10-15 minutes until the charcoal is lit, then put the top grate on with my Maverick ET73 wireless thermometer setup. I have tried different strategies for manipulating the vents. After speaking with Char-Griller support, they told me to open both the top and the bottom to a 1 setting. Whenever I do that, it just takes off well into the 300's. I tried starting off with the top completely closed, and the bottom just barely open. It creeps up nicely, but then dies after about 30-45 minutes. So I tried opening the top just barely so that the little half-circle shape is open, and the bottom is just barely open, but it either dies or takes off again up into the 300's. I'm seriously considering returning this unit and buying an electric box smoker (Masterbuilt, or something similar) so that I don't have to keep tending this thing. Any last minute tips before I give up?
