Second use of a MPS. 9 lb butt, started at 7:30 last night, had trouble getting smoke and regulating temp. Finally got both settled after a couple hours. Reached 154 degrees about 3:30 AM. Has stayed at that temp until now...just increased to 156. I've read about the stall, but this seems excessive. Been at this temp for 6 hours. Any words of wisdom, advice besides wait? Have not foiled...stopped smoke at 3:30 AM. Now at 14 hours into this smoke...
