I'm doing my first Venison Kielbasa smoke in my new 40" MES. I started out at 160° for 12 hours and only hit 125° internal temp. I really thought I'd be at 140° by that time or a little higher. I'm not at 180° and the internal temp is only at 131°. Before anyone asks, I have used another temp probe and I got the same exact internal reading. I'm trying to get to 152° without melting all the fat in the Kielbasa. Am I doing something wrong? I had a 30" MES previously and never had this problem.
