Stihl 011 av Chainsaw Engine. New Piston and Ring, New Oil Pump with new oil filter, new vent tube and filter, New Ignition Module, the points were cleaned and reset to manufacturers specs. New Muffler Spark Arrestor, Refurbished Carburetor (cleaned and rebuilt, with new diaphragms and gaskets), new sparkplug. Tested and started on 3rd pull and ran great. No noticeable leaks. Clutch is still good, some where but usable. Will throw in a used bar and chain for Stihl 011AV. Outer crankcase shows signs of wear, no cracks. Good condition, considering the age.
