About how many pounds of lump was that? What kind? Is the bottom of your charcoal basket above the level of the intakes?
It was a pretty nice day around here yesterday with little to no wind. Having one vent open only 1/2 way sounds about right for a temp of 240. Mine will do 225 on half a vent with no wind and warm ambient temps.
