Alright, so I spent the day at the machine shop working on the drum. Powerwashed, steam cleaned, and hand washed with soap and water. Back down to good clean stainless...well mostly. Taking the comments about oxygen or lack thereof into consideration. I made larger intakes. I always had (2) 1.5" intake tubes but the holes going thru the drum were 1". Not anymore. And I still am not sure if maybe the charcoal could have been a problem so I pitched it. So clean drum, more air, new charcoal...and a thirty pack of keystone light...I plan to light her back up and see what happens. Again thanks to all for the help.
