I got my new BGE on Wednesday. Great first meal. Last night, it had trouble staying hot, but I was cooking tuna, so no big deal. It turned out fine.
Tonight, I'm doing 2 sittin chickens and it just won't stay hot. I've got both drafts wide open & have even spent many minutes blowing into the bottom one trying to keep it stoked.
Charcoal is a new dry bag.
I wouldn't think 2 cookings (maybe even 1, since it was this way last night) would clog any holes.
