Hi latest problem! Hoping someone has some knowledge on stihl throttle trigger springs. I've changed from double handle to single and the second hand throttle had the return spring unattached and I can't see where it connects to the orange trigger piece. The spring lays flat over the on off switch and is secured in place with about an inch of straight tail. If anyone's dismantled one it's probably straight forward but parts diagrams don't show how they all connect unfortunately. Not sure if I can attach photos that may help?
