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.
With this carburetor it is only possible to 
correct the setting of the high speed 
screw within fine limits.
Standard Setting
: Shut off the engine.
: Check the air filter and clean or 
replace if necessary.
: Check the spark arresting screen* in 
the muffler and clean or replace if 
necessary.
: Turn the high speed screw (H) 
counterclockwise as far as stop (no 
more than 3/4 turn).
: Turn the low speed screw (L) 
clockwise as far as stop and then 
turn it back 1/4 turn.
