How to Tune a Husqvarna 323L Trimmer

The Husqvarna 323L trimmer is among the top choices for professional landscapers because of its E-Tech high performance engine, straight shaft and versatile gear box that is designed for heavier, more rugged, commercial applications. Despite its solid reputation and durable build, the 323L needs regular maintenance. Part of that upkeep includes regular tuneups. Tuning your Husqvarna 323L takes approximately 30 minutes. Replacement spark plugs can be purchased at your local lawn care shop or retail home improvement store.
