Hey all, I just picked up my first smoker at a garage sale for. It is a Perfect Flame vertical propane smoker. Despite it being $15, it's in pretty good shape. The issue I'm having is that when I turn the gas on more than halfway I notice flame coming from somewhere other than the burner. I'm not sure if this is a feature or what but it seems odd. Here is a picture of the spot its coming from without the flame, and one with it. Any ideas what might be going on?
