What Does the Carburetor Do?
The carburetor meters fuel and air before the mixture enters the engine for combustion. The correct mixture is important for starting, idle quality, acceleration, and overall engine performance.
The carburetor works together with the air filter, throttle system, fuel system, and intake components.
Signs Your Carburetor May Need Replacement
A carburetor may require inspection or replacement if you experience:
-
Difficulty starting.
-
Poor or unstable idle.
-
Engine hesitation during acceleration.
-
Reduced engine power.
-
Engine stalling.
-
Poor throttle response.
-
Fuel leakage around the carburetor.
-
An engine that will not maintain proper operation after other fuel-system components have been checked.
Similar symptoms can also be caused by a clogged air filter, fuel-system problems, ignition issues, or intake leaks.
Installation Note
Carburetor replacement should be performed carefully and according to the applicable STIHL service procedure.
-
Shut off the chainsaw and allow the engine to cool completely.
-
Remove the appropriate air-filter and carburetor-access components.
-
Disconnect the applicable fuel and throttle connections.
