To adjust the carburetor and eliminate sparks and sputters, look for the carburetor adjustment screws on your STIHL trimmer. Turn the H screw and the L screw clockwise all the way to adjust the settings, and then turn each screw back one rotation. The H screw may require a quarter turn adjustment either way.
