Husqvarna 120

2-Stroke

The Husqvarna 120 is a 38.2cc 2-stroke chainsaw positioned as an occasional-use homeowner model for light property tasks — limbing, small firewood, and storm cleanup — accepting 13" to 15" guide bars. It runs a Zama carburetor. Husqvarna's SmartStart system reduces initial pull resistance. The 120 shares service part families with the 130 series for good parts availability. Routine maintenance items are the spark plug (NGK BPMR7A or Champion RCJ6Y), air filter, primer bulb, and fuel lines. Draining the fuel system before storage prevents the most common no-start condition on low-use homeowner saws.
