18.5 WSM Temperature Control

I have had my 18.5 WSM since May and have enjoyed it very much. I still have some difficulty controlling the temperature. It seems that every few minutes I need to adjust the vents to either lower the temp or to bring it back up. The time I'm expecting for what I'm smoking is much shorter than I have expected. I am using a clay saucer over a Brinkman water pan. I have tried to let the temp of the WSM adjust itself before putting the meat on. I'm using Stubb's charcoal which is fantastic. I will use up my Kingsford when I'm grilling some items on my OTG. Is there something that I am overlooking when controlling the temp on my WSM?
 
Hey Chuck!
Are you using the Minion Method and catching (adjusting you vents) on the way up?
Vent adjustments usually take about 15-20 min on my WSM to stabilize.
Are you mopping or spritzing?
Every time you lift the lid you should get a little temp spike, more-so with the clay dish if the lid is off for awhile.

Chuck, how are you measuring temps? If you are using the WSM attached thermometer it is considered very inaccurate. How many smokes have you done? The WSM is less accurate early on...you need to develop some smokey stuff to help seal the WSM.

Also, make sure the door on the WSM fits well. If it is loose, the temp will fluctuate. Finally, make sure your unit is not "out of round" so that you are not drafty around where the parts of the WSM come together.

Hey Chuck, Temperature adjustments on the smoker are not instant. Once you make bottom vent adjustment you have to leave the WSM alone for 10-15 minutes to let your tweaking take effect. With a little patience you will have your smoker chugging along at your desired temperature.

I have a Maverick 732 wireless thermometer. The door seems to be very secure. I have done 4 smokes to date. The last smoke I did was rib tips. I used the standard method as I did not expect a long smoke process. I was trying to keep the temp in the 235-250 deg range.
 
The Standard Method is fine for 3-6hr cooks, but its better suited to run @ temps 300+°
For your temps you would have an easier time using the MM and catching it on the way up.
