I just bought a 22.5 OTG on Craigslist.  I have a Genisis, but I want to try charcoal and the smokenator.  Anway, the kettle is a little wobbly and the top vent is a little loose.  Two questions: Is there a way to tighten the vent?  Is there a way to remove some of the wobble?  It feels like it is wobbly where the legs meet the kettle.  Thanks for all of the great info on the forum!
