4180 122 3000 STIHL Spring – Genuine OEM Carburetor Spring
The STIHL Spring (4180 122 3000) is a genuine OEM carburetor spring designed for use on select STIHL professional trimmers, brushcutters, edgers, hedge trimmers, KombiMotor units, and multi-task tools equipped with C1Q-series carburetors.
This spring is an internal carburetor component responsible for maintaining correct lever tension and return action within the fuel metering or throttle control system, depending on carburetor configuration. Proper spring tension is essential for accurate fuel delivery, smooth throttle response, and stable engine operation.
Manufactured to STIHL factory specifications, this OEM spring provides the correct tension, strength, and durability required for long-term carburetor performance.
Replacing a weak, stretched, or broken spring helps restore proper carburetor function and prevents running, idle, or starting issues.
