Engine Management
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.
General Information
The carburetor comes from the factory
with a standard setting.
This setting provides an optimum fuel-air
mixture under most operating
conditions.

Turn high speed screw (H)
counterclockwise as far as stop (no
more than 3/4 turn).
With this carburetor it is only possible to
correct the adjusting screws within fine
limits.
Turn the low speed screw (L)
carefully clockwise as far as stop,
then turn it back 1/4 turn.
If the setting is too lean there is a
risk of engine damage due to
insufficient lubrication and
overheating.
Adjusting Idle Speed
