Hi Duck,glad you fixed your problem,to regulate your temps with this smoker
i will recomend this,that you open the chimney all the way,open your side fire box damper about 1/3rd of the way.
you should hold a steady 225 degrees.
also replace your cook chamber thermo,or get a remote,also,and maybe it's just me but i have a thermo on my fire box also,it tells me at a glance what i need to do to keep a steady temp.good luck.
