Purchased at a estate sale. Bought it home and took the air hose to it; extremely dirty. Found out it needs a new Sprocket & Clutch. Clutch number (68362).  I did put in a new Fuel Filter. Could not test the Compression or Spark as it pulls hard;  Starter Rope pulls easy when not attached to Saw. Needs new Air Filter.  Fuel Lines are good.  The Bar is good, just needs edge's deburred .  The Handle is missing a chunk of the black plastic on top. Really think that this quality Saw could be put back in working condition; right now I am Chainsaw poor and don't really need it.   Model no. 10403A  - Ser, no. 293300206.  The Bar & Chain will be removed for smaller shipping box.
