Video Of the heat riser spring in action.

(This video idea is credited to DADS50- mine is just a different angle) I angled the viewpoint to show the heat valve opening & closing.
Edit- I am aware this thread is settled, but the video "explains" a lot instead of wording it into confusion. Somebody chime in if the one I have on video is not functioning correctly...
