Hi Everyone, I´m Alex from Spain, using Stihl for yrs, currently an MS260 chainsaw and FS250 strimmer.
So the question is... strimmer stopped sparking, new coil and spark plug, still no go, disconnected coil cut off lead and still nothing so new coil dodgy ? anything else to check ? Thanks

Did you disconnect the kill wire at the coil? If not your wire could still be grounded somewhere. If you did, I suspect bad coil.
