BioLion Carburetor Replacement for Husqvarna 330LK 130L 130C - Complete Kit with Primer Bulbs & Spark Plug

High-quality replacement carburetor kit engineered to restore reliable starting, smooth acceleration, and stable idling for Husqvarna 330LK, 130L and 130C string trimmers.

This BioLion 330LK carburetor assembly is a complete aftermarket solution designed to swap directly into compatible Husqvarna engines and address common fuel-delivery problems without professional re-machining. The kit pairs the carburetor body with essential service parts—primer bulbs, fuel fittings, a new spark plug, filters and gaskets—so you can replace worn components in one session and reduce downtime. Before ordering, verify your trimmer’s model and the original part number (531127910 replacement) to ensure correct fitment.

How will this carburetor improve starting and acceleration?

Worn or clogged carburetors commonly cause hard starting, slow acceleration and poor throttle response. Installing this BioLion unit replaces aging seals, jets and the primer system to re-establish correct fuel-air mixture and restore predictable engine behavior.

• Includes two primer bulbs to ensure proper fuel filling of the bowl.
• New fuel filter and fuel line reduce clogging and varnish build-up.
• Replacement nipples and gasket eliminate leaks that hamper acceleration.

What exactly is included in the kit and why it matters?

BioLion supplies a full service kit so you don’t have to source multiple small parts after removing the old carburetor. Having matched parts in the box speeds installation and reduces the chance of mismatched fittings or leftover components.

• 1× carburetor body matched to 531127910 replacement specifications.
• 2× primer bulbs, 2× nipples, 1× fuel line and 1× fuel filter for fuel delivery integrity.
• 1× air filter, 1× gasket and 1× spark plug to refresh ignition and air flow.

Is installation difficult for a home mechanic?

Basic hand tools and a modest level of mechanical comfort are sufficient to install this replacement on most trimmers. The kit is designed to be a near-drop-in swap that avoids carburetor re-jetting in many cases, but take your time and follow safe fuel-handling practices.

• Simple tool list: screwdrivers, metric sockets/wrenches, pliers and cleaning cloths.
• Replace the air filter and spark plug while the carburetor is removed for efficient service.
• Check all fittings and primer bulbs for airtight seals before first start-up.

How does this part help prevent recurring engine issues?

Replacing a worn carburetor and associated consumables removes sources of air leaks, fuel contamination and weak spark that commonly lead to stalling, black smoke, or oil-like crankcase contamination. Fresh components restore correct metering and reduce the frequency of repeat repairs when combined with regular maintenance.

• New gaskets and nipples stop tiny leaks that upset fuel-air mixtures.
• Fuel and air filters trap debris that would otherwise enter the engine.
• Included spark plug ensures proper ignition timing and cleaner combustion.

Who is this for: This BioLion 330LK carburetor kit is aimed at homeowners, landscapers and small-engine technicians who own Husqvarna 330LK, 130L or 130C string trimmers and need a turnkey replacement to fix hard starts, poor acceleration or fuel-leak symptoms. It’s ideal if you want a complete set of fresh consumables to return a trimmer to reliable, daily-use condition without hunting for separate parts.
