Any ideas? Lid is sealed, plenty of charcoal / lump (use a combination), so I'm just scratching my head as to why...
Mine runs along pretty well with one cap off (3/4in) and valve half way open. If you close it down too much it can't get enough air and will drop the temp. It may actually "backdraft" and fluctuate the temp when it exhales and then inhales a large amount of air. Drums take a while to settle in, set the valves and leave it, for 30 min, before adjusting. small adj should only be needed.
