Just picked up a very very nice 034 super that needs a piston. I never use anything but OEM on the Stihls and was looking on Ebay for one, when I ran across one with part # 1119 030 2000 that says it's 48mm but that part number googles for an 038...anybody know if this is the same piston with a different part number? Can't believe they would be that different, except possibly for the wrist pin diameter maybe? Or maybe the piston skirt? Can somebody tell me who knows for sure...thanks for any help!
