Description
Overview:
The Inlet Control Lever is a small but critical carburettor component used to regulate fuel delivery to the engine on a wide range of Stihl machines, including the FS38 and FS45. This genuine Stihl part (1125 121 5000) is typically a precision-stamped steel lever designed to operate the needle valve reliably for consistent fuel metering. Replacing a worn or bent lever restores proper fuel control, improving starting, idle stability and throttle response. Suitable for brushcutters, hedge trimmers, blowers, Kombi engines, drills, cut-off saws and chainsaws, it integrates neatly within the carburettor with no modification. Built to Stihl's specification, it is a direct-fit replacement that supports long service life and dependable day-to-day operation.
Key Features:
- Genuine Stihl part for assured fit and compatibility
- Precision lever geometry for accurate fuel metering
- Durable metal construction for wear and deformation resistance
- Helps cure rich/lean running caused by a worn metering lever
- Supports easier starting and stable idle when correctly set
- Direct replacement with no modification of the carburettor body
- Suitable across many Stihl machines for streamlined maintenance
- Supplied to OEM standards for long-term reliability
Typical Applications:
Used during carburettor service or overhaul when addressing hard starting, poor idle, hesitation or flooding linked to metering control. Ideal for routine maintenance on Stihl brushcutters, hedge trimmers, blowers, Kombi engines, chainsaws and cut-off saws operating in gardening, landscaping, forestry, construction and grounds maintenance. Replaces bent, worn or corroded levers to restore correct fuel delivery.
Also known as:
Metering lever, needle valve lever, carburettor inlet lever, carb fuel control lever, metering arm. These terms describe the same internal carb component that actuates the inlet needle to control fuel level in the metering chamber.
