I have not run my new EM-1 for a few weeks now, so I fired it up the got it on the track yesterday. But something sounded off to me. when I run the smoke, there is a rattle noise that I did not remember being there before. I don't think this is normal. Attached is a video of the stack. It only seems to happen on the main smoke unit, the whistle steam is normal.
SO
#1 What is going on?
#2 How can I fix this?
As always thanks for the help in advance!
