Important Carburetor Compatibility Note
The supplied STIHL parts information associates this part with three carburetor configurations:
-
C1M-S226
-
C1M-S207
-
C1M-S145
However, several models in the application list reference the part under the air filter / spacer flange assembly rather than directly under the carburetor assembly.
For this reason, do not rely on the model name alone. Check the equipment's parts diagram, carburetor identification, and original part number to confirm that 4144 120 0603 is the correct replacement.
How the Carburetor Works
The carburetor controls the mixture of fuel and air entering the engine.
As the engine operates, air passes through the intake system while the carburetor meters the required amount of fuel. The resulting mixture enters the combustion chamber, where it is ignited to produce engine power.
A properly functioning carburetor helps provide:
-
Reliable starting
-
Stable idle
-
Smooth acceleration
-
Consistent engine speed
-
Proper power under load
Signs of Carburetor Problems
A carburetor or its related components may require inspection if you experience:
-
Hard starting.
-
Engine stalling.
-
Rough or unstable idle.
-
Poor acceleration.
-
Engine hesitation.
-
Reduced power.
-
Inconsistent engine speed.
-
Fuel leakage.
-
Difficulty adjusting the carburetor.
Before replacing the carburetor, inspect the air filter, fuel filter, fuel lines, primer system, and other related components because these can produce similar symptoms.
Why Replace the Carburetor?
A worn or damaged carburetor can prevent the engine from receiving the correct air-fuel mixture. This can result in poor starting, unstable operation, and reduced performance.
Replacing the applicable carburetor component with the correct STIHL OEM 4144 120 0603 part helps restore the intended fuel and air delivery system.
