I did my first butt today on my MES 40. Bought a 6 pound boston butt I picked up at the butcher shop. While I seasoned my MES 40 for the first time I put the temp gauge I had in my grill into the smoker to see what the temp difference was. This morning I got up at 6:15 started the MES to warmup and pull the butt out of the fridge to let it warm up for a couple of minutes before I started it. 7:00 it was in the smoker and everything looked like it was going great. About 3 hours in I stuck the temp probe into the butt and the temp was already well above 140 degrees and I knew I needed to get ready to wrap it (I used foil pan and covered tightly). By 1 PM the but was already at 190. I thought that was a little quick so I pulled my grill thermometer out and it evidently was broke because the needle dropped to zero. So I dropped the temp on the smoker down to the 240 it was suppose to be to start but couldn't slow down the heating of the meat. So I took the butt out when it hit 200 IT (checked with meat probe and thermometer and put in a cooler with towels all around it. Is there any problems with it cooking so fast even though I made sure it the IT was where it should be? I ordered a Maverick ET732 that should be here Wednesday so I hopefully don't have this problem again. Thanks for the help.
