I am in my second run with my new MES. (this time 5lb of pork shoulder and 5lb of beef shoulder) and I have noticed that 3 or 4 times the unit "burps" smoke out the vent and chip loader. I am guessing I am having a flare up of some sort. Has anyone had this happen before, and is there something I can do? Or is this no big deal and I should just enjoy another beer?
