Chainsaw Repair

The original Zama carb on the FS-55 had some white corrosion inside the metering valve chamber, otherwise was clean as could be. The HS worked fine but there was no fuel on the LS. I ran wires through the three holes that go into the venturi and took the LS needle out and run wires in there and through the hole in the metering chamber floor that feeds the LS. But still no LS fuel.

So I had to pay like $29 total for a new carb at the Kubota (Stihl) store nearest the house. It worked perfect without adjustment.
