Engine Management
Exhaust emissions are controlled by the design of the fundamental engine parameters and components (e.g. carburation, ignition, timing and valve or port timing) without the addition of any major hardware.
Adjusting the Carburetor
General Information
The carburetor comes from the factory with a standard setting.
This setting provides an optimum
With this carburetor it is only possible to correct the adjusting screws within fine limits.
If the setting is too lean there is a risk of engine damage due to
insufficient lubrication and overheating.

English
NTurn the high speed screw (H) counterclockwise as far as stop (no more than 3/4 turn).
NTurn the low speed screw (L) carefully clockwise as far as stop, then turn it back 1 full turn.
Adjusting idle speed
Engine stops while idling
NOpen the low speed screw (L) one full turn.
NTurn the idle speed screw (LA) clockwise until the chain begins to run – then back it off 1/2 turn.
Chain runs when engine is idling
NOpen the low speed screw (L) one full turn.
NTurn the idle speed screw (LA) counterclockwise until the chain begins to run – then turn it another 1/2 turn in the same direction.
If the chain continues moving when the engine is idling, have your saw checked and repaired by your servicing dealer.
Erratic idling behavior, poor acceleration (even though low speed screw is open one turn)
NIdle setting is too lean: Turn the low speed screw (L) counterclockwise until the engine runs and accelerates smoothly.
It is usually necessary to change the setting of the idle speed screw (LA) after every correction to the low speed screw (L).
