I realized that your post was intended for another purpose right after I sent it. I was chewing over why I would have to remove the pin. Thanks. The link didn't work on my iPad either - might be a shortened address in the link.
I sent note to Dennis because I made all of the other adjustments and checked the lid all around with some folded paper to make sure it clamped and was uniform. It works better than it did, and will now shut down pretty well, but smoke still floats out.
