I'm a half hour into my second some on my char-griller/side fire box. I'm doing a chicken in parts and 2 fattys. I seem to have trouble getting my temp up to 300 to 325 for the chicken. I'm using Cowboy Brand chunk hardwood charcoal. Have about 3 chimney loads with 2 of them lit. My temp is around 250 at the cooking grate near the fire box. Any help would be appreciated. Will try q-view later.
