I'm using a Bradley 4 rack digital unit because my MES is broke.I made a batch yesterday and they were in my 4 rack digital for around 9 hours. The results were very good. So, today I put another batch in to smoke and they have been in there for 11 hours and seem to be stuck on 135 degrees internal. The smoker is set for 170 degrees. Am I doing something wrong here, should I pull them now or wait for the 152 degree internal temp?
