Don't mean to question you but I have never had a full chimney light in 20 min. And when I rush it before the top is fully going thinking that when I dump that the unlit will be on the bottom and catch, always results in lower temps and all coals going grey instead of red hot coals
Andrew,
I think you'll get better responses if you post a new question. My opinion is that the entire chimney doesn't need to be lit. I like to see a good glowing core in the chimney and the flames coming over the top and I'm good to go. Usually that means the top coals are just starting to ash over on the edges.
