What causes a Husqvarna 555 XP carburettor to leak fuel?
If the carburettor on your Husqvarna Chainsaw is leaking fuel, it could be due to a loose or faulty fuel pipe, a hole in the diaphragm, a worn needle/needle tip, or a sticking control system. Other potential causes include a control system set too high, a leaking control system, or a loose cover on the carburettor pump side.
Why is the idling uneven on my Husqvarna Chainsaw?
Uneven idling in your Husqvarna Chainsaw can be caused by several factors: a blocked fuel filter or fuel line, a leaking inlet hose, or loose carburettor mounting. Other potential issues include a worn throttle valve axle, a loose throttle valve screw, a worn throttle valve, a leaking control system, or a worn control system’s centre knob. A hole or leaking diaphragm/cover plate, or a leaking crankcase could also be the cause.
