Quick question, does anyone have any mods to help a Weber Kettle lid fit without losing smoke from under the lid. A couple months back I restored an old Performer I got off of CL and the lid never really fit right from the start. It was a little bent probably from someone dropping it and I got it to fit but it's almost like the lid is too big for the bowl. When its on the kettle I can move it all around as it doesn't fit snug. Is this normal? Will it affect air control for long slow cooks? Just curious. Thanks in advance for any tips.
