HEEEEEEEEEELP!!!!! I started the coals up about an hour ago in the firebox. The firebox is nice and hot, but the temp in the grill area wouldn't get past 100. I noticed there was a lot of heat near the firebox, so I turned the coal pan upside down to try to help it distribute. Now, I can't even get close to 100. I have the smoke stack open most of the way, and can see heat coming out of it, but the grill lid is only warm to the touch. I have the firebox vent open all the way. What am I doing wrong?
