Picked up one of these the other day but having a hard time leveling temps. When it starts off it is hot near the stack. Then after about an hour or two it swaps sides and the firebox side runs hot. Yes I have tuning plates and have played with the arrangement ALOT just can seem to get it to level off. Did a test run again last night and closiest I could get it was about 40 degrees side to side. It holds heat great and recovery is amazing but just can't seem to figure out how to keep level temps. Does anyone else have one of these and did you figure out how to level the temps?
