I'm excited because I finally found something that is definitely broken! Ha.
The heat riser valve spring is definitely broken:
Here's a quick video of me manually actuating it:

I'm googling, but I'm having a hard time figuring out how important this is.
What affect will a broken spring have on engine operation, and what do I have to do to fix it?
Thanks!
