I have an 8# butt ready to go overnight, but I'm a little worried about my setup. I was at the bottom of a bag of lump and dumped it all in when firing it up. That left me with a higher fill than normal, above the first seem. I didn't have room for the pizza stone drop rig, so I put the stone on the grid. I'll be able to put the butt on the raised rack and essentially have a raised indirect with a very full fire box.
My concern comes in the temp control. I'm finding the lower vent needs to be more open than normal to allow enough air in to get the temp to 250. Normally it'd be about the width of a nickel, now it's probably a half inch. I'm worried if it starts breathing better during the night the temp will spike and I'll be in bad shape in the morning.
Anyone ever had something like this come up before? I'm tempted to just run it a little low and deal with it in the morning if the fire ends up going out. I know I can recover from too low temp/fire out, but I'll be toast if it's too high.
Cheers all -
