I'm using my new WSM for the first time today to cook 2 7 lb butts. I did a minion start with 45 lit and a full ring. Shut down vents to 25% at 200 degrees. When the smoker came up to 250 degrees (as measured by the stock lid therm) I shut one vent completely and am now running at a consistent 240* for the last hour and a half. Should I shut another vent to get the temp down closer to 225 or just let it do it's thing? Everything seems fine and I'm happy with the ease of operation. Just curious what the experienced guys think.
