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).
Carburetor Type: Walbro WT-498-1 (see manual for updated specs)
