Husqvarna 125L

2-Stroke

The Husqvarna 125L is a 25.4cc 2-stroke straight-shaft trimmer in Husqvarna's consumer range for residential grass trimming and light property maintenance. It runs a Zama carburetor and accepts standard bump-feed heads with .095" line. Features SmartStart and a combined choke/stop control. The 125L is mechanically related to the 128L and 128LD, sharing several service parts. Common wear items are the primer bulb, fuel lines, air filter, and fuel filter. Draining fuel before off-season storage prevents stale-fuel diaphragm hardening in the Zama carb, the most common cause of seasonal no-start conditions.
