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.
The carburetor comes from the factory
with a standard setting.
This setting provides an optimumfuel-air
mixture under most operating
conditions.
With this carburetor it is only possible to
make corrections with the adjusting
screws within fine limits.
