I am having a problem with my stihl fs120 trimmer. After you start the trimmer it will run for a little time an then quit. It then won't start. I have rebuilt the carburetor,replace the fuel filter,replaced fuel lines and used fresh gas mix. Any help on whats wrong. Also does anyone know what type carburetor or make is on the fs120?

Thank you for any help you can give me. Charlie

Does it have spark after it dies?
