This is the second time I've tried smoking pork butts for pulled pork. The first time took forever but today, well, this is nuts isn't it? I am stuck at 171 on a simple 2 lb pork butt, and it's been over 9 hours. I had my first slightly larger one come off ver an hour ago, having reached 195 IT. I did a larger 3.5 lb butt for a neighbour which has also come off, but even then, those came off after ver 8 hrs, when I understand it should generally take about 1.5 hours per pound. I've also tried two different probes and they read roughly the same, so I don't believe the fault lies with the probes. Temp has been pretty variable, but between 225 - 250 all day. Can anyone advise what I may be missing? It's making me nuts - and hungry with the wait!
