Description
Overview:
The Carburetor C1Q-S216 / C1Q S190 is a genuine Stihl replacement carburettor designed to restore correct fuel metering and smooth running on Stihl two‐stroke brushcutters. Built around a durable die‐cast alloy body with precision‐machined passages, it regulates the air-fuel mixture so your engine starts reliably, idles steadily, and accelerates cleanly under load. This unit is a direct-fit for popular machines such as the Stihl FS 38 and FS 45, matching the original linkage, choke and mounting pattern. Supplied to Stihl specification under OEM reference 4140 120 0621, it is suitable for a wide range of light to medium‐duty grass trimming and brush cutting work. Choosing a genuine Stihl part helps maintain performance, fuel efficiency and engine life while reducing downtime from hard starting or erratic running.
Key Features:
- Genuine Stihl part for assured compatibility, quality and calibration with the FS 38/FS 45 family
- Robust die‐cast alloy body for long service life in outdoor, dusty and high‐vibration environments
- Accurate metering of the air-fuel mix for easy starting, stable idle and smooth throttle response
- Direct bolt-on replacement; accepts the original throttle, choke and fuel line connections
- Helps reduce poor running symptoms such as bogging, surging and flat spots under load
- Built for modern pump fuel use and daily operation in landscaping and grounds maintenance
- Replaces Stihl references including 4140 120 0621 and selected 4140 120 0618 variants
Typical Applications:
Used on Stihl brushcutters and grass trimmers for garden maintenance, landscaping, estate care and light commercial grounds work. Ideal when an engine becomes hard to start, won't idle, or hesitates on acceleration due to a worn or contaminated carburettor. Suitable for routine refurbishment to keep equipment running efficiently through the season.
