My valve is moving well.
But it will not stay open even when really warm.
When I pull the throttle I can see it opens but then it closes again. Bad spring ?

I have a new spring so I think I will change it.

Just have to be careful not braking the clamps holding the spring and then remember the position so it points the correct way.
1/2 of a turn to tighten the spring as I remember?
