My 6.5 lb butt has been on a 225 degree smoker for a little less than 4 hours and is at 202 degrees according to the probe. I smoked it until it hit 160 then double wrapped it in heavy foil & put it back on. I have a chicken & some ribs to smoke & don't want to over smoke the butt so that's why I wrapped it. Why in the world would it be at 202 so quickly? I've been smoking for years and never encountered this. It never stalled or anything like it usually does.
