042-048 muffler
042-048 muffler; The muffler for Stihl 042,and 048 are the same.The part number is 1117-140-0612,this a 2 part assembley of parts 1117-145-0702[inlet side]and 1117-145-0802 [outlet side] and also an internal screen.The subject arises about the durability of these saws quite often.I have 2 of the 048's and 1 042 and can only add,that they are little powerhouses.The 048's came from the west coast and were probabley used by timbermen,and the 042 came from Ill. and was used by an arborist.Considering the type of service they were subjected to and the fact that they still run like race horses,this proves ,at least to me,that there is some degree of design in this model.Al
