The carburetor is the heart of your Husqvarna leaf blower's fuel system. When your blower won't start, runs rough, or dies out after a few minutes, a dirty or failed carburetor is almost always the culprit. Ethanol in modern fuel gums up the carburetor jets and needle seat, starving the engine of fuel. Before you replace the whole carburetor, try a rebuild kit — it's a fraction of the cost and solves most running issues.
We carry OEM Husqvarna carburetor kits and complete carburetors for all major blower models. A carburetor kit includes gaskets, seals, jets, float needles, and o-rings — everything you need to restore fuel flow. Enter your Husqvarna model number below to find the exact carburetor assembly or rebuild kit that fits.
Ethanol-blended fuel oxidizes and leaves varnish inside the carburetor. If your blower sits unused for more than a month, the fuel dries and gums up the jets and needle seat. The engine loses fuel flow — either won't start or dies during operation. A carburetor rebuild kit cleans out the varnish and restores every fuel passage to like-new condition. For severe clogging, a complete OEM carburetor replacement is the faster fix.
OEM Husqvarna carburetors are engineered for your exact blower model — jet sizes, float height, and needle seating are all matched to your engine's air intake and fuel pressure. Aftermarket carburetors often have incorrect jet sizing, leading to lean running (surging, overheating) or rich running (fouling spark plugs, black smoke). Spend the extra $20 to $30 for the genuine Husqvarna carburetor or rebuild kit — you'll get reliable starting and smooth idle.
A carburetor kit (rebuild kit) includes gaskets, o-rings, jets, float needle, and seals — you disassemble your existing carburetor, replace the internal parts, and reassemble. A complete carburetor is ready to bolt on. Kits work well for mild varnish or cracked o-rings. If the carburetor body is cracked, the float is damaged, or the needle seat is pitted beyond cleaning, buy the complete OEM assembly. Most Husqvarna blower carburetors cost $35 to $70 complete — worth the cost for peace of mind.
The model number is stamped or printed on a label on the blower housing, usually near the fuel cap or air filter cover. It starts with numbers like 125B, 145BT, or 326BTS. Enter that model number in the search box above — we'll show you the exact carburetor and rebuild kits that fit. If you can't find the label, the engine model (Husqvarna-specific or licensed from another brand) is another way to verify the right carb.

On Husqvarna leaf blowers, look for the model-number label on the main housing, often near the fuel cap or air filter cover. You may also find it on another area of the blower housing, so clear away dirt before reading the characters. The model usually combines numbers and letters, such as 125B, 145BT, or 326BTS. Type that number into the model number search to pull up the parts matched to your unit.
