Correctly adjusted carburettor

A correctly adjusted carburettor means that the machine

accelerates without hesitation and the machine 4-cycles a

little at max speed. Furthermore, the cutting attachment

must not rotate/move at idling. A too lean adjusted low

speed needle L may cause starting difficulties and bad

acceleration.

A too lean adjusted high speed needle H gives lower power

= less capacity, bad acceleration and/or damage to the

engine.

A too rich adjustment of the two speed needles L and H

gives acceleration problems or too low working speed.

MAINTENANCE

Final setting of the idling speed T

Adjust the idling speed with

the screw T, If it is necessary

to readjust. First turn the

idle speed adjusting screw T

clockwise until the cutting

attachment starts to rotate/

move.

Then turn, counter-

clockwise until the cutting

attachment stops. A correctly

adjusted idle speed setting

occurs when the engine runs

smoothly in every position.

It should also be good

margin to the rpm when the

cutting attachment starts to

rotate/move.

CAUTION! Contact your servicing dealer, if the idle speed

setting cannot be adjusted so that the cutting attachment

stops. Do not use the machine until it has been properly

adjusted or repaired.

High speed needle H

The high speed needle affects

the machine’s power, speed,

temperature and fuel

consumption. A too lean

adjustment on the high

speed needle H (the high

speed needle H is screwed in

too much) gives a too high

speed resulting in engine

damage. Do not allow the

engine to run at full speed

for more than 10 seconds.

Apply full throttle and turn

the high speed needle H

slowly anticlockwise until

the engine runs unevenly.

The high speed needle H is

then turned slowly clockwise

a little until the engine runs

smoothly.

Note the engine should be

run unloaded when

adjusting the high speed

needle. Therefore dismantle

the cutting equipment, nut,

support flange and disc drive

before adjusting the high

speed needle. The high speed

needle is adjusted correctly when the machine ‘splatters’ a little

. If the machine smokes heavily at the same time as it ‘splatters’

heavily the adjustment is too rich.

NOTE! For optimum setting of the carburettor, contact a

qualified servicing dealer who has a revolution counter at his

disposal.
