What am I doing wrong? Each cook I stir up the old lump and flush the ash through to the bottom. I then add new lump on top and generally use one SureStart Firelighting Square - torn into 4 pieces. I put one piece at the 12/3/6/9 oclock positions in the lump and light all 4. Vent open, top open until the fire gets going. Generally 10 minutes or so. But inevitably the fire is almost entirely in the top part of the egg away from the vent, even though I also used the starters towards the bottom of the egg (closer to the vent). What's the deal with this?
