Hello all. New to smoking. Just seasoned my Olkahoma Joe's Highlander last night and noticed that my right side temp Guage consistently runs between 30 and 50 degree cooler than the right. Strange because this is right next to the firebox. I installed firebox and smoke chamber gaskets, lowered the exhaust stack to grate height and added tuning plates. Seasoned with Royal Oak lump charcoal and a few pieces of chunk hickory for smoke. Played with my inlet and had no trouble raising smoker up over 300 degrees and lowering back down but no matter where I stabilized the heat at the right side read cooler between 30 and 50 degrees. Any input here folks?
