I got a chance Monday afternoon to do another test run.
This time I filled the coal basket 3/4 full with lump. Once the pit hit a temp of 170 I added 2 large splits of cherry. I turned the fan on manual mode at its lowest setting. Pit settled in at 243 within about 15 minutes. A little hotter then I would of liked but it held that temp for better then 2 and a half hours before it started to drop a little.
Going give it one more test run before the weekend cook. This time I'm going to go with a little less lump and I large split of cherry to start. Want to see if I can get closer to the 225 mark for the same amount of time.
