Low speed jet L
Try to find the highest idling speed, turning the low speed
needle L clockwise respectively counter-clockwise. When the
highest speed has been found, turn the low speed needle L 1/
4 turn counter-clockwise.
CAUTION! If the sweeper rollers rotates/moves while the
engine is idling, the T-screw should be turned anti-clockwise
until the sweeper rollers stops.
Fine adjustment of the idle speed T
Adjust the idling speed with the T-screw, if it is necessary to
readjust. First turn the idle speed adjusting screw T clockwise
until the sweeper rollers starts to rotate/move. Then turn, anti-
clockwise until the sweeper rollers 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 sweeper rollers starts to rotate/move.
WARNING! If the idling speed cannot be
!
adjusted so that the sweeper rollers stops,
contact your service workshop. Do not use
the machine until it has been correctly
adjusted or repaired.

High speed jet H
The high speed jet H affects the engine power, speed,
temperature and fuel consumption. If the high speed jet H is
set too lean (screwed in too far) the engine speed will be too
high and cause engine damage. Do not let the engine run at
full speed for more than 10 seconds.
Apply full throttle and turn the high speed jet H very slowly
clockwise until the engine slows down. Then turn the high
speed jet H very slowly anticlockwise until the engine starts to
run unevenly. Now turn the high speed jet H slowly clockwise
a little way until the engine runs smoothly.
Note that the engine should be run unloaded when adjusting
the high speed needle. Therefore dismantle the sweeper
rollers and roller shafts before adjusting the high speed
needle.
The high speed jet H is adjusted correctly when the machine
burbles a little. If the machine races then the setting is too
lean. If the engine produces a lot of smoke and burbles a lot
then the setting is too rich.
H
CAUTION! For optimum adjustment of the carburettor,
contact a qualified dealer/service workshop that has a
revolution counter at their disposal.
Correctly adjusted carburetor
When the carburetor is correctly adjusted the machine will
accelerate without hesitation and burble a little at maximum
speed. It is also important that the sweeper rollers does not
rotate/move at idle.
If the high speed jet H is set too lean it will result in less power,
less performance, poor acceleration and/or damage to the
engine.
If both the L and H jets are set too rich it will results in
acceleration problems or too low a working speed.
