Adjusting the Carburetor
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.
Your carburetor does not have a high
speed adjusting screw (H screw).
Adjustmentof maximum enginespeed is
not necessary.
The carburetor is set at the factory to
provide an optimum fuel-air mixture
under most operating conditions.
Idling and part-load emissions are
minimized by limiting the idle mixture.

:
Check the cutting blades and clean
if necessary (they must be clean,
move freely and not be bent or
warped).
Check the air filter and clean it if
necessary.
:
:
Warm up the engine.
Carefully screw the low speed
screw (L) down onto its seat. Then
open it one turn counterclockwise
(standard setting, L = 1).
