Had the Ol Osburn cranking tonight at first when the stove top got to 750 I was worried but then I realized with a load of ash in there it was probably normal. So i cut the air intake all the way down and she stabalized at 750 for about ten minutes then started to decline and now shes cruising at 600. Im sure the wife will be dressing skimpy this winter , I know pics or it didnt happen.
