My second try smoking a 3.5 Boston butt in my masterbuilt, the meat stalled at 155 for a long while after 5 hours so I decided to go ahead and wrap it and put it back in and raise the temp. I can't get the the internal temp to move above 166 or so, I raised the smoker temp to 275. What should I do? It seems that it's taking far too long to smoke a small butt but then again I'm new at smoking... But also a life long fanatic of quality eastern Carolina style pulled pork. Any advice would be welcomed
