Chainsaw Repair

Now on that chain of which I have no idea what it was ,Oregon at one time made 1/4 chisel in both full and skip .The original s-25 had 1/4" chain .Fact I've got the drum and a chain but it's semi not chisel  .

I've mentioned the fact many times that Ralph Nader was instramental in getting that non guard type chain taken off the market .If however a person could possibley find the stuff those little saws even in stock form will literally fly though wood .It was the fastest chain for little saws I had ever seen .The last I'd seen any of that chain was probably around 1977-78 .
