Ok second smoke in my life and trying to nail his 8.65lb Boston butt, this is the first time i a getting to use my new Mav 732. WSM says 230 ET732 says 250*. So i put it in the oven at 170 and its still 25 degrees off, i inspected the probe and noticed when i put the butt on i touched the probe and some juice and rub got on the end and is now blackened on. I have cleaned it and replaced it on the wsm. I have a potatoe standing by to replace the little metal clip if its still off and if that doesnt work ill perform the boil test and up date you all. Hoping the juice burned on was the problem.
