Been struggling with fire/temperature control. With the help from a member on another forum we got it figured out...at least the end to end deal. Previously my firebox end would read 325*, middle would read 265* the far end 250*. I likened the FB being so high because the FB is pushed into the CC. About a third of the FB. And yes the dials are calibrated. We got it so that all 3 of them are within 5*...add a small split at 250*, temperature will peak at 275*. Add a split at 255* and it will jump to 325*. Add a large split and,it will either sky rocket to 375* or smoke like an old small block Chevy on a cold winter morning. Got curious...clamped a ThermoWorks probe on the cooking grate. In front of one of the recently calibrated thermometer. The tip of the thermometer is about an inch above the grate. Thermoworks read 298*....dial read 265*. This "normal"?
