Only done a couple of cooks on my new WSM 57cm. Noticed that it wasn't shutting down when all the vents were closed and would carry on burning for hours afterwards, also leaking quite a lot of smoke from the lid - drum join.
The web wisdom suggested that it would need 12 or so cooks to gum up and prevent leaks, but being impatient I decided to try and source some gasket material in the UK.
Found & ordered some of this stuff: http://shop.vitcas.com/stove-thermal-ta ... -377-p.asp
Just fitted it to the top of the drum & will be interested to see if it reduces the smoke leaking from the join. Really easy to fit after a quick clean with Cillit Bang. Will give it a try without doing the door, but have enough to do the door if required.
Can't seem to upload pictures...
