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).

The Husky 257XP has a 3.4 hp engine and is built on the same chassis as the very similar, but non-XP, Husqvarna 359. The Husqvarna 357XP is a 56.5cc chainsaw that was produced between the years 2003 and 2011. The 357XP was replaced in 2011 by the 562XP chainsaw. The 357 was sold with a 16, 18, or 20″ bar, and it’s recommended for use with 13 – 20″ bars.

It’s the perfect all-around saw for everything from felling, to limbing and to cross-cutting.

357 XP features:

  • Low vibe for smoother handling
  • Adjustable oil pump for changing the flow in different seasons/climates
  • Magnesium crankcase that withstands higher RPMs and tougher use
  • Air injection and centrifugal air cleaning system improves engine life
  • Three piece crankshaft makes it more durable
  • Smart Start feature reduces starter cord resistance by up to 40%
  • Ergonomic front handle offset at 7 degrees to reduce fatigue
