Hello, Thanks again for all the feedback.
I tried to run her today but it seems to only be firing on one cylinder. The position of the heat riser does not matter anymore. I could not check for leaks as the engine was not running at all. The spark plugs are pretty white from the last 150 miles and I am still waiting for the new ones to arrive.
The engine was running hotter than normal because I was going trough mountains with about 50mph, but it ran with almost the same setup fine before. I suspect I lost the heat riser spring and from there it started overheating. What else can I look for?
