A Stihl FS91RZ trimmer loses power after using it a while. Changed out the spark plug but still doing the same thing. Any suggestions what I should be looking at? It has been like that since purchased. Was taken back a few times and all they did was “adjust” it to the point the warranty ran out. Was thinking the starting coil may be weak?
