I got a medium BGE for Christmas, and have been learning its ins and outs. We have had some great meals from it, and nothing has come out raw or burned a crisp, so I'm not doing too bad so far (more likely its just pretty easy to use). I have one remaining problem though. The dome doesn't set down squarely on the base. I have taken the lid off and reattached it several times, and made sure to use the included assembly tools: the 3 small orange wedges and the white plastic strip for the hinge. No matter what I do the dome remains offset. Initially there was a significant smoke leakage around the back, but that got fixed by resetting the lid once. The picture below shows the problem near the handle. There is, of course, the reverse problem (dome too far back) at the back of the Egg. The sketch only installation instructions, which show using the 3 wedges and the white plastic strip when attaching the dome, lead me to suspect this is a common problem (or result of some common mistake that new owners make). Any suggestions or hints would be appreciated.
