Description
4226 120 7100 STIHL Throttle Shaft with Lever – Genuine OEM Part
The STIHL Throttle Shaft with Lever (4226 120 7100) is a genuine OEM carburetor component designed for use with select STIHL handheld power equipment equipped with C1Q-series carburetors. This part plays a critical role in throttle control by regulating the opening and closing of the carburetor throttle plate in response to operator input.
A properly functioning throttle shaft and lever assembly ensures smooth throttle response, stable idle, and accurate engine speed control. Worn, bent, or damaged throttle shafts can cause sticking throttle operation, erratic engine speed, or poor performance.
Manufactured to STIHL factory specifications, this OEM component ensures precise fitment, correct geometry, and long-term durability under professional operating conditions.
