BioLion 330LK carburetor is a direct aftermarket replacement for Husqvarna 130L, 130C and 330LK trimmers, built to restore smooth starting and reliable throttle response.

If your Husqvarna trimmer is hard to start, hesitates under load, leaks fuel, or emits black smoke, a worn or clogged carburetor is often the cause. This BioLion assembly is made to match the fit and function of part #531127910 and ships as a complete maintenance kit so you can replace worn parts in one repair session.

How will this carburetor improve starting and running behavior?

Replacing a failing carburetor restores the correct air-fuel mixture and primer action required for consistent ignition. Expect easier cold starts, fewer stalls, and steadier acceleration when the engine demands change.

• Replaces worn internal passages that cause flooding or lean running.
• Includes primer bulbs to restore quick fuel draw for cold starts.
• Addresses black smoke by correcting excessive fuel delivery.

Is installation difficult and what problems does it fix?

The replacement fixes oil/fuel leakage, starting difficulty, acceleration failure, and excessive smoke when those issues are caused by the carburetor or associated small parts.
