DonR9,
You have to decide which instructions to follow. I learned last night that there are three versions, one for fluid and two for chimneys. I think this is why my two cooks ran cool, as I followed the printed instructions and lit just 40 coals, but last night I found the lighting how-to video on PBC's site and in it Noah lights a whole chimney. Big difference there. I'm going to do that next time.
I don't think they are setting the vent at the factory any more. Mine came swinging loose, too.
