Adjusting Husqvarna T425 Chainsaw Carburetor (for manual carburetor)

Husqvarna T425 Chainsaw chainsaw carburetor guide. The carburetor has been factory adjusted to provide the optimal engine air/fuel flow. Instructions for standard settings to adjust the idling screw, turning either clockwise or counter clockwise. Learn how to set the idling screw correctly if the engine is cutting out or idling incorrectly.

Learn how to check the spark plug for a good electrical spark, cleaning or replacing if required. Air filter cleaning and replacement is described in the operator manual. Detailed carburetor PDF manuals are available from this website.

Carburetor – General Chainsaw Adjustment

Adjusting the carburettor involves adjusting the engine to the local conditions e.g. climate, altitude, fuel and type of two-stroke oil. The carburettor is equipped with three adjustment options.
L = Low speed jet
H = High speed jet
T = Idling adjustment screw

The L and H jets adjust the fuel flow to match the airflow that the throttle valve opening allows. Turning them clockwise makes the fuel/air mixture weaker (less fuel in relation to the amount of air) and turning them anti-clockwise makes the fuel/air mixture richer. A weak mixture increases the engine speed and a rich mixture decreases the engine speed.

The T screw controls the throttle position when idling. Turning the T screw clockwise gives faster idling; turning it anti-clockwise lowers idling speed (see manual for complete guide).
