First time using the Egg last night for a Pork Butt. Got the fire going and messed with the temp for about 2 hours before putting on the 8lb Butt. Once the butt when on I had the temp pegged at 250. But went on at 9pm. at 12:30am the temp was 270 which I figured would be perfect for me to get some sleep and it might drop somewhere between 225 and 250 over the course of the night. I woke up at 4am and checked on the temp and the smoke was pouring out, temp was 350? I stuck a thermometer in and internal temp was 206 which pissed me off. I was hoping for a 12hr smoke instead it was 7 hours. What did I do wrong?
The bottom vent was open maybe 11/4 inch and the top was just barely cracked. I'm talking barely. Why is my temp so high? Also, when I shut the top and bottom vent completely it took the egg 30-45 mins to start dropping temp at all.
