First run is going well so far. Doing baby backs low and slow with some pecan chunks. Pegged 250 in about 1/2 haour and holding steady since. My question has to do with the smoke. I used 3 large chunks of pecan and put them on about 10min. before the ribs went on. I had a good amount of smoke for the first 30-45 min, but has now disappeared. Should I be concerned. I absolutely love this thing. The aroma is a thing of absolute beauty.
