Adjusting the Carburetor

carburation, ignition, timing and valve or
port timing) without the addition of any
major hardware.

Start and warm up the engine.
Adjust idle speed with the idle speed
screw (LA) so that the cutting tool

The carburetor comes from the factory
with a standard setting.
This setting provides an optimum fuel-air
mixture under most operating
conditions.
Fine Tuning
A slight correction of the setting of the
high speed screw (H) may be necessary
if engine power is not satisfactory when
operating at high altitude or at sea level
or after changing the cutting tool.
With this carburetor it is only possible to
adjust the engine idle speed within fine
limits.!
