Help! I am new to the smoking world and just got a WSM. I did a 5 lb pork shoulder last weekend (55 degrees and slightly windy) and could not get the temp above 205 and needed to add charcoal twice in the process. Tried same recipe again this week (50 degree and steady rain) and had the same problem. A friend who smokes said to learn on charcoal and graduate to wood but the charcoal seems to breakdown and fall through the grate and can't hold its heat. I am using Kingsford and also have mixed in hickory wood chunks.The shoulder is excellent it just takes 10 hours to do and there are other recipes that I want to try where I need to maintain temps in the 250 to 300 range. Any suggestions would be greatly appreciated. Thanks.
