Description
4244 120 0611 STIHL Carburetor 4244/11 – Genuine OEM Fuel System Part
The STIHL Carburetor 4244/11 (4244 120 0611) is a genuine OEM fuel metering component designed to regulate the air and fuel mixture in select STIHL backpack blowers and mistblowers. This carburetor plays a critical role in engine starting, throttle response, fuel efficiency, and overall performance under professional operating conditions.
Over time, carburetors can become clogged, worn, or internally damaged due to ethanol fuel deposits, diaphragm wear, dirt contamination, or extended storage. A failing carburetor may cause hard starting, rough idle, hesitation during acceleration, surging, stalling, or reduced engine power. Replacing it with the correct OEM carburetor restores factory fuel delivery performance without replacing the entire engine assembly.
Manufactured to STIHL factory specifications, this genuine carburetor ensures precise fitment, proper fuel regulation, and long-term durability in demanding commercial applications.
