Ok, I put 2 racks of spares on earlier this morning and temp started out good. Now it is a couple hours later and my temp has dropped and I cannot get it to return. I dumped a new chimney full of lit coals in about 30-45 minutes ago and it is still below 200. I'm still learning this so any help would be appreciated. Oh, I am using a cheapo Brinkmann offset smoker.
