In

the

carburetor,

fuel

is

mixed

with

When

the

engine

is

test

run

at

the

factory,

the

carburetor

is

adjusted.

A

further

may

be

required,

according

to

climate

and

altitude.

The

carburetor

has

one

adjustment

possibility:

T

=

Idle

speed

adjustment

screw.

Idle speed adjustment (T)

Check

that

the

air

 fi

is

clean.

When

the

idle

will

not

rotate.

If

adjustment

is

required,

close

(clockwise)

the

T-screw,

with

the

engine

running,

until

the

cutting

attachment

starts

to

rotate.

Open

(counter-clockwise)

the

screw

until

the

cutting

attachment

stops.

You

have

reached

the

correct

idle

speed

when

the

engine

runs

smoothly

in

all

positions

well

below

the

rpm

when

the

cutting

attachment

starts

to

rotate.

If

the

cutting

attachment

still

rotates

after

NOTE

Some

models

sold

in

areas

with

strict

exhaust

emission

regulation

do

not

have

high

and

low

speed

carburetor

adjustments.

Such

adjustments

may

allow

the

engine

to

be

operated

outside

of

their

emission

compliance

limits.

For

these

models,

the

only

carburetor

adjustment

is

idle

speed.

For

models

that

are

equipped

with

low

and

high

speed

adjustments;

carburetors

are

preset

at

the

factory

Minor

greater

than

90

degrees,

as

engine

if

you

are

not

familiar

with

this

type

of

adjustment,

seek

assistance

from

your
