So after i wrapprd the ribs, i couldn't get temps over 130°-150°. since the ribs were foiled i cleared out some ash, lit a new 1/2 chiminey and added a half chimeny of unlit coals and then the lit coals. After 20 minutes the temps are around 165°. Could it be that the foiled ribs are absorbing the heat?
