Husqvarna String Trimmer Parts & Repair Guide

Husqvarna string trimmers are built for reliability, but carburetors, primer bulbs, and fuel lines are the most common repairs — especially after winter storage or using old fuel. When your Husqvarna won't start, runs rough, or loses power, the carburetor is almost always the culprit. Ethanol in fuel gums up the float needle and jets, choking the engine before it gets going.

We carry OEM Husqvarna carburetor kits, fuel line assemblies, and primer bulbs to get your trimmer cutting again. Enter your model number to find the exact parts for your machine.

• Won't start or hard starting: Carburetor clogged from stale fuel; primer bulb cracked or won't draw fuel
• Runs rough or cuts out: Spark plug fouled; fuel filter clogged; carburetor needs cleaning or rebuild
• Weak power or no power: Throttle cable stretched or snapped; carburetor running lean; air filter clogged
• Trimmer head won't spin: Drive shaft broken; recoil starter won't engage; spark plug missing fire
• Pull cord stuck or won't recoil: Recoil starter spring broken; rope tangled inside housing

Husqvarna String Trimmer Parts — Frequently Asked Questions

What's the most common reason a Husqvarna string trimmer won't start?

A clogged carburetor from ethanol fuel is the #1 culprit. Fuel left in the tank over winter or for more than 30 days breaks down, gumming up the carburetor's tiny jets and the float needle. A carburetor rebuild kit often fixes the problem without needing a full replacement. If the primer bulb is cracked or won't draw fuel, replace it — it's a $5 to $10 part. Always drain old fuel and run the trimmer dry before long storage, or mix fresh fuel with fuel stabilizer.

How do I find my Husqvarna string trimmer model number?

The model number is stamped or labeled on the shaft, near the engine block, or on the clutch housing. Common Husqvarna models include 115iL, 128LD, and 525LS. Write down the full model number and any serial number before ordering parts — Husqvarna's part compatibility can vary significantly between model generations. Use our model number lookup to confirm you're getting the exact carburetor, spark plug, and fuel line for your trimmer.

Can I use a universal trimmer head on my Husqvarna?

OEM Husqvarna trimmer heads and spools are always the better choice — they're engineered for your machine's drive shaft diameter and bearing tolerances. Universal aftermarket heads often have fitment issues, cause wobbling, or fail to feed line correctly. If your head is cracked or won't bump-feed line, order the OEM replacement for your model. Trimmer line diameter also matters — check your manual for the correct.095" or other size your head requires.

Why is my Husqvarna string trimmer losing power mid-cut?

Check these in order: (1) Clean or replace the air filter — a clogged filter starves the engine of oxygen. (2) Check the spark plug — a fouled or gapped plug cuts ignition. (3) Inspect the fuel line for cracks or blockage. (4) If fuel line looks good, the carburetor is likely running too lean — a rebuild kit or full carburetor replacement is needed. OEM Husqvarna carburetors are priced competitively and come pre-tuned for your model.

Husqvarna String Trimmer Model Number: Where to Look

Husqvarna typically places the model number on a label or stamping on the shaft near the engine block or on the clutch housing. If dirt or fading makes it hard to read, wipe the area clean and check the operator's manual for a matching identification entry. Write down the complete model number, including letters and numbers, before entering it in Repair Clinic's search bar. Type it into our model number lookup and the catalog narrows to parts made for your unit. This model-based filter covers the entire Husqvarna string trimmer and its associated parts, rather than narrowing you to one category. It is the quickest way to be sure the part fits before you order.
