I have a Weber 22.5" Silver, and I have two problems:
1. Temp climbs even with bottom vents completely closed
2. Medium white smoke instead of TBS. (Food tastes great in spite of this, so fixing this is lower priority than #1.)
I rather suspect my problems are operator error, so I'll explain how I set it up. I divide the charcoal grate about in half with four firebricks, and almost fill the shy 1/2 side with Kingsford. I leave a little space at one end of the crescent for 12 lit coals from my chimney. I put the lit coals in, and it comes up to temp (225*F) in probably about 30 minutes. I have the top vent wide open and opposite the coals. I measure the temp with a laboratory thermometer stuck in through one of the top vent holes so that the bulb is just a little higher than the meat. Once I'm ready to put the meat on, I add a small chunk, maybe 1" x 1" x 2" of well-seasoned cherry on top of the burning coals. The temp slowly climbs, and when it reaches my upper limit, I put a few ice cubes on the food grate on top of the burning coals to calm it down. I'll post some pics in a little while in case anything is less than crystal clear.
