Engine Management
Adjusting the Carburetor
Adjust idle speed with the idle speed
screw (LA) so that the cutting
attachments does not turn.
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.
The carburetor comes from the factory
with a standard setting.
This setting provides an optimum fuel-air
mixture under most operating
conditions.
