Will my saw need to be tuned after adding a muffler?

Yes, your saw will likely need adjustment after installing a new muffler to ensure it runs properly with the changed airflow.

• Carburetor-equipped saws: These usually require manual tuning to prevent running lean, which can cause engine damage.

• Stihl saws with M-Tronic: The system will need a reset or recalibration after the muffler change.

• Husqvarna saws with AutoTune: AutoTune generally adjusts automatically over time but may require some running time or manual intervention.

Proper tuning helps maintain optimal performance, extends engine life, and ensures safe operation.

Because tuning procedures vary widely across models, it’s best to follow the manufacturer’s specific instructions for your saw.
