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 fuel-air
mixture under most operating
conditions.
Changing the setting of the high speed
screw alters the engine's power output
and the maximum off-load engine
speed.
If the setting is too lean there is a
risk of engine damage due to
insufficient lubrication and
overheating.
Standard Setting
N
Shut off the engine.
N Check the air filter and clean or
replace if necessary.
N Check the spark arresting screen
(country-specific) in the muffler and
clean or replace if necessary.
