Keep your Stihl 011 chainsaw operating reliably with genuine OEM replacement parts from Repair Clinic. The Stihl 011 is an older professional-grade two-stroke chainsaw from Stihl’s classic lineup. The 011 AV and 011 AVT are related variants: the AV designation identifies the anti-vibration system and the AVT designation identifies the upgraded two-point anti-vibration system with additional damping. As an older engine platform the Stihl 011 is especially susceptible to carburetor diaphragm hardening from years of ethanol-blend fuel exposure. Repair Clinic stocks genuine Stihl OEM parts for the 011 including the Stihl carburetor parts, Stihl air filter parts, Stihl spark plug parts, and Stihl chain parts.

Stihl 011, 011 AV, and 011 AVT: Professional Two-Stroke Chainsaw Service
The Stihl 011 uses a two-stroke engine with a diaphragm carburetor specific to handheld professional chainsaws. The 011 AV and 011 AVT are successively improved variants with anti-vibration systems, with the AVT providing two-point damping. Most carburetor, fuel system, and ignition components are shared across the 011 platform variants. As an older engine the 011 carburetor diaphragm may have hardened from years of ethanol-blend fuel exposure, making cleaning insufficient and complete carburetor replacement necessary. The chainsaw repair help section covers 011 carburetor service, chain sharpening, and oil pump diagnosis.
Most Replaced Parts on the Stihl 011
Carburetor for the Stihl 011
On older 011 engines the carburetor diaphragm may have hardened from years of ethanol-blend fuel exposure. A hardened diaphragm cannot flex adequately to pump and meter fuel, and cleaning alone cannot restore it. Complete carburetor replacement is required when cleaning fails to resolve lean running or hard starting on an older 011.
Air Filter for the 011
Replace the air filter at the start of each cutting season. On an older professional chainsaw operating in dusty or sawdust-heavy conditions, frequent filter inspection is necessary to prevent abrasive damage to the carburetor and engine.
Spark Plug for the Stihl 011
Annual spark plug replacement maintains reliable starting and clean combustion in the two-stroke engine. Always use the fuel mixture ratio specified in the Stihl 011 owner’s manual.
Drive Chain for the 011
Replace the drive chain when it no longer holds tension within the adjustment range, or when links are cracked or bent. Always confirm the chain pitch and gauge from the bar label or owner’s manual before ordering.

Stihl 011 Chainsaw Parts FAQ
What is the Stihl 011 and how do the 011 AV and 011 AVT variants differ?
The Stihl 011 is an older professional two-stroke chainsaw. The 011 AV adds an anti-vibration system and the 011 AVT adds an upgraded two-point anti-vibration system with additional damping. Most fuel system and ignition components are shared across all three variants.
Why does my Stihl 011 run lean even after carburetor cleaning?
On an older 011 the carburetor diaphragm may have hardened from years of ethanol-blend fuel exposure. A hardened diaphragm cannot flex adequately to pump and meter fuel. Cleaning cannot restore a hardened diaphragm, and complete carburetor replacement is required.
How do I find the correct chain size for my Stihl 011?
Confirm the chain pitch and drive link count from the bar label on the guide bar currently installed on the chainsaw, or from the owner’s manual. Always use these specifications when ordering a replacement chain.
How do I adjust the chain tension on the Stihl 011?
Loosen the bar mounting nuts, turn the chain tension screw clockwise to increase tension until the chain hangs snugly against the bar without sagging, then retighten the mounting nuts firmly while holding the bar tip upward.
