I have recently knocked off the top part of my nautilus off the base by accident, as such the adjustable airflow ring band came off. There was a spring that allows your to properly adjust the airflow holes.
I am wondering if this product the replacement part: "http://www.aspirecigonline.com/aspire-nautilus-accessories-p-74.html
If so, what is that pin for?
See attached for my problem.
