Probably asked a million times, but my search skills suck. I have a CharGriller grill with the side smoker box. I can't keep the cooking temperature even throughout the smoke and have a hard time even getting it to saty above 200* after 2 hours or so. I am starting with a load of charcoal (kingsford standard ones) in the side smoker pit area and when it is almost all white, I spread it out and put some wood chunks on top. I keep adding some charcoal when it looks to be 75% burnt out. This in itself is probably wrong, but I don't know for sure. Anyways, after doing that routine for 2-3hrs, I can't seem to get a hot fire anymore and it throws off the cooking time. I generally keep the smoke box vent halfway open and the grill stack vent the same. I am not having any trouble getting the smoke into the food, just can't keep the "fire" lit. Any hints, ideas, knowledge would be great, and don't worry about hurting my feelings, as I have my big boy pants on.
