Why is my Husqvarna 135 Chainsaw idling uneven?
- KKimberly BaldwinSep 7, 2025
If your Husqvarna Chainsaw is idling unevenly, consider these potential causes: a blocked fuel filter, a blocked fuel line, a leaking air intake hose, loose carburettor mounting bolts, a worn throttle valve pivot, a loose throttle valve screw, a worn throttle valve, a sticking needle valve assembly, a leak in the metering system, a worn metering system centre knob, a hole in the diaphragm, a leaking control diaphragm/cover plate, or a crankcase leak.
