It's a Lang model 60. I've been running it all summer. Have 20 or 30 runs on it so far. The problems I'm seeing are this: 1. Uneven temperatures across the smoking chamber. At the firebox end it's almost 100 degrees hotter than the end furthest from the firebox. The middle seems to match up with the thermometer. Below is a Rock's Stoker temperature chart from a test run I did with no meat in the chamber. The temp was set at 280 degrees and it was maintaining that in the middle of the graph. The pit temp probe was clipped onto the Lang thermometer. The smoking chamber was 310 degrees on the firebox end, 280 in the middle and 220 on the end furthest from the firebox. Is there anything I can do to even out the temperatures on this thing? 2. I cannot get the temperatures as high as I want with just a coals fire (using firewood but when it's burned down to no flames left). I've had large glowing beds of coals in the firebox and the temp stays below 200 degrees. In order to run higher (250 to 280) I have to keep the fire flaming, which means I have to keep fresh wood in the box. Not a problem, but I can't get the good thin blue with flaming wood. I get more of the billowing white smoke. If I was to try to use the burn barrel method to preburn the wood and put coals in the firebox, I would never get enough heat. Is this something that can be overcome or is it simply a characteristic of this type of smoker?
