I finally found it!
It is on the rope side of the engine by the muffler.
It is under the handle that comes up from the rope side.
I had to spray some brake cleaner on it and wipe it and it showed up.
And yes it is like the other two saws in "Dot Matrix".
I am glad to get that done, we have a theif on the mountain that has already broke into a neighbors place and stole their chainsaw, blower and weedeater.
We are going out of town for a few days and when we get back I am going to hide the vehicles inside the garage and catch me a crook!
Thanks for your help.
