Everywhere I read people are trying to lower the temp. I 've only had my WSM a week, but I have problems raising the temp. Of the 3 cooks I did last weekend 2 I had all the vents 100% the entire cook. temp held steady but would not climb. What to do to raise temp? I wanted to cook my Turkey between 325 ~ 350 I couldn't get a bit higher than 307. water pan was empty. I used 2 full chimney's and the coals were completely lit before I assembled. Weather according to my log: Light Rain With Thunder, 66° Breezy, Wind SW 16MPH, Humidity 65% but I had the WSM just inside the garage to block wind.
