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).

What does the XP G mean on a Husqvarna chainsaw?

543 XPG for XP= Extra Power and G= Generator for Heated handles and or carb heater.

The power is stated as 2.2 kW for the 543 XPG

Japanese Strato technology from Zenoah is in the engine. It involves using two “charges” of air to the cylinder via two different intake ducts with their own dampers, where one is not mixed with petrol but is just pure air, it goes completely outside the carburettor. The clean air is drawn into the overflow duct to be ahead of the air mixed with gasoline/oil when the exhaust gases are to be pushed out and accompanies the exhaust gases and is not used in the combustion. It becomes like a cushion of fresh air between the exhaust gases and the fuel/air mixture, and then you avoid losses that are normally found in a two-stroke engine when part of the intake air goes straight out together with the exhaust gases.

Husqvarna 543xpg has low weight, good branching properties. Improvements on previous saw designs are the oil pump does not flow out oil at idle and which has a larger adjustment interval, the pump bladder for the fuel, it is more easily pulled in the starter, air filter access, it has two sword nuts and has less vibration according to factory data.


Air Injection
Centrifugal air cleaning system removes larger dust and debris particles before reaching the air filter. This results in reduced air filter cleanings and improved engine lifeX-Torq
Delivers lower fuel consumption and reduced exhaust emission levels in accordance with the world´s most stringent environmental regulations.
Adjustable oil pump
Allows you to control oil flow depending on application and weather conditions.
