I am using my Masterbuilt Electric Smoker to smoke a 6.5 lb pork butt. I put it in around 9 and have kept the temp steady around 235. We are now 2.5 hours later and I am already at 160 internal temp. I know there is the stall, but does this seem to be cooking to fast to anyone else? Has anyone else had this problem in the past, if so what did you do? Any help would be appreciated.
