When your Stihl leaf blower stops running or loses power, the problem is almost always one of a handful of common parts. Stihl blowers are built to last, but carburetors get gummed up from ethanol fuel, recoil starters wear out, and fuel lines crack. Repair Clinic stocks genuine OEM Stihl parts — not aftermarket substitutes — so you get the exact fit and performance your blower was engineered for.
Stihl is dealer-exclusive when new, but we carry the full range of OEM replacement parts for every Stihl leaf blower model. Enter your model number to find the carburetor kit, spark plug, fuel line, primer bulb, or impeller you need.
Need help finding your model number? Browse Stihl leaf blower parts by model or check the engine block or product tag on your blower. Once you have it, Repair Clinic's model lookup shows you every compatible part for your exact machine.
Hard starting on a Stihl blower is almost always the carburetor. Ethanol in modern gasoline gums up the float, needle valve, and jets inside the carb. A Stihl carburetor rebuild kit cleans out the old fuel residue and restores proper fuel atomization. If the blower has sat unused for more than a season, a carb kit is your first move before replacing the whole carburetor.
Stihl makes different carburetors for different blower displacement and design. A BG55 uses a different carb than a BR600 backpack blower. The safest way is to enter your full model number — it's stamped on the blower housing or engine block — into Repair Clinic's lookup tool. We'll show you the exact OEM carburetor kit and rebuild kit for your machine. Never assume two Stihl models use the same carb.
A Stihl carb kit includes new gaskets, seals, float, needle valve, and jets — everything that wears or gets clogged by ethanol. For light gumming or seasonal storage issues, a kit saves you $20 to $30 and is just as effective as a full carb. If the carb body itself is cracked or the kit doesn't solve the problem, then a full OEM carburetor is the next step.
No. The impeller (fan blade) is precision-balanced and spins at high RPM. A cracked blade throws the balance off, causes vibration, and will eventually fail completely. Weak airflow is often your first sign. OEM Stihl impeller replacement ensures your blower performs at rated CFM. Aftermarket blades rarely fit as precisely, leading to noise and premature wear on the bearing.
