Hi all, new here. My dad brought me a used Stihl MS250. He showed me how to start it and he shut it down by pushing the switch up to 'off'.
The next day I removed the cover to inspect the condition of the air filter and since then, I can't kill the saw by using the off switch. I push up and nothing happens. I end up having to choke it out to kill it. Did I lose a small piece of metal when I removed the rear cover? I see how the contact is plugged to the yellow wire and understand that when I push the switch up it rotates the assembly and pushed down on the contact spring. The switch assembly is nylon and the grey wire that plugs into it just slide into a nylon slot. Where's the metal??? I figure it would use a metal to short the ignition to kill it.
Any help would be great. I know the saw works, he was using it on a job before he came up to visit. Thanks.
Here are a couple pics.
