My MS 430 C has been going great for 18 months but lately the lever which shuts off the engine has ceased to function.
I slide it up for STOP and it jumps back to RUN.
To stop the engine I put it to foll choke.
Looking inside whenever cleaning the air filter I see nothing unusual, but how does one know what it all should look like? Is there a source of drawings / photos of this area? Or, is there a reason this problem might arise?
Thanks Phil
I do not own this chainsaw so my observations might not be worth anything at all.
But ...
Usually this sort of engine kills the motor by shorting it out. When you take off the housing covering the lever, you should be able to see the problem immediately. You may also find that there is a detent that has some sort of problem ... perhaps nothing more than just filled with crud.
My 2 cents worth. Enclose an SASE for a full refund.

not sure on the stihl but most saws have a spade type electical connecter at the switch i would check that to be inplace first, if it looks ok pullt the connecter off the switch and try gounding out to the saw body by hand, if it kills the engine you need a new switch. ross
Bill & Ross - Thanks. I look for the shorting path but cannot immediately see it. Something may be missing.
