A 44.7mm piston kit for the Stihl MS271, replacing 1141 030 2012. The MS271 was built with two cylinder designs, so compare your cylinder with the listing photos before ordering. A scored piston is usually a lean condition, so pressure and vacuum test the crankcase and fix any air leak or fuel fault before the new piston goes in. Measure ring end gap in the bore, use a ring compressor and fit the circlips fully.
