Hello, I just checked the heat riser and the thing is moving freely and the bi-metal-spring is gone. I suspect me running the engine lean burned out the spring wich caused the carb to overheat. I did not run it yet as I am waiting for my friend to be the emergency hauler.

If the weight is down to the left side if I look at it from the front, is it open or closed? It seems it was stuck in that position.
