I have a E-330 with the smoker kit. I am smoking a pork butt right now and can't get the temp to go under about 260F. Only the burner right by the smoker box is on the lowest it can be. I have read that it is best to keep the temps to about 225F. Does anybody have any suggestions? I hope I can do some acceptable smoking this way until I can work a WSM into my budget.
