Dave and Larry, thanks for the advice. I have spent the better part of the last couple of days figuring out the mechanics of how the #3 cycles through a smoke. Also, worked on the advice on how to control the oxygen to get a smoother and longer smoulder of the wood. In my last run, I put in 5 ounces of wood and ran the #3 for three hours at 225 degrees. I got good smoke for three hours and when I took the firebox out of the #3 I had three blocks of wood that collectively weighed 1.5 ounce. So, I only smouldered 3.5 ounces of wood during the three hours.
I put in two racks of Babybacks about 10:00 a.m. this morning. I'm going to let them go for four hours, then slather the ribs with my sauce and put them back in for 20 to 30 minutes.
