I've had my large BGE for about a month, and it has been nothing short of spectacular, as has been the support from all of you.
Here's my problem -- the first day I got the Egg, I fired it up for steaks and it went to 600 degrees in no time. Most of what I've been cooking since then has involved lower heat, such as smoking, cooking fish etc. But the last couple of times I tried to go hot, including last night for pizza. And it's a real struggle now to get it above 400. I made sure the ash holes on the firebox grate were clear, emptied out the ash from the bottom, and put in several inches of BGE lump charcoal. Used 2 BGE firestarters, each broken in two, so I had four ignition points, and it lit off just fine.
But after 40 minutes, with top and bottom air vents wide open, I was still at 390, and climbing SOOO slowly.
The pizza was great, but this ain't right.
