I have a different problem. My temp won't get above 150 to 175, that is if I believe the thermometer. Not sure I do until I go to the store and get a portable one I guess. But I have the vents both below and the smokestack on my Master Forge ($149 from Lowe's) barely open.
I did finally figure out I wouldnt go through wood chips so quickly if I soaked them.
I'm a former user of a huge barrel smoker with an offset fire box. Got tired of spending so much time stoking and buying wood. I went to this smoker now that I live alone thinking I could do the Ronco set it and forget it routine. But it appears that isn't entirely true.
