Mine was off by about 3/4 of a turn. At first I was just turning the cover back 3/4 of a turn but didn't like how loose it felt. Then I marked and drilled a 1/16 inch hole (smallest bit I had) directly in front of the wick. For now I just have a round paper punched piece of clear packing tape covering the original hole. When I get around to it I'll pick up some silver solder (lead free) and try melting it into the hole. I've never tried soldering chrome before so hopefully it adheres to the chrome or the metal under the chrome. If not, I'll figure something out.
I also like the slightly looser draw I'm getting with a 1/16 inch hole.
