I finally received the long awaited mystery saw.A lot of you were thinking it was a 6-10,sorry to say it's the sorriest "saw" I ever bought.The engine is siezed tight as a drum,the muffler is so rusted that if I sneeze it'll crumble off,the choke rod is siezed to the carb,the recoil is siezed & when I took it off to see what was wrong the clutch started falling apart.Yeah,it's the sorriest "saw" I ever bought.Needless to say it's going back.BTW,it's a 2-10,too light to be a 6-10.I've never seen so many cob webs in a saw in my life.And the real sad part was that it still had old rancid fuel in it that must be at least 30-40 yrs.old.
