I just purchased a used Stihl MS362C with Mtronics (got a direct hit from H. Michael and still have much to do). This saw doesn't have the linkage to the Master Control Lever (cold start/Run/Stop lever). I am having trouble locating the part to order online. I see how I can replicate what the linkage does to choose cold start - and the saw starts and runs. I'm confused what the lever is supposed to do to shutdown the saw when raised to the stop position. It has a wire coming from the Master Control Lever, but raising it (without the linkage) while the saw is running does not shut down the saw. If anyone could tell me how to find the linkage online to order, and how it shuts down the saw, I would be very grateful! Thankyou.
