2 EMISSION ADJUSTMENT GUIDE
2-1 General adjusting rules
A. Before starting the unit for adjustment, check the following items.
1. The correct spark plug must be clean and properly gapped.
2. The air filter element must be clean and properly installed.
3. The muffler exhaust port must be clear of carbon.
4. The fuel lines, tank vent and fuel filter are in good condition and clear of debris.
5. The fuel is fresh ( > 89 octane : RON) and properly mixed at 50 : 1 with “ISO L-EGD”or “JASO FC”2-
stroke oil.
6. The gear case assembly with blade set adjusted clearance properly must be installed for proper engine
loading.
B. Start and run engine for 2 minutes alternating engine speed between WOT and idle every 5 seconds.
Adjust idle adjust screw to 2900 +/- 200 r/min. If engine does not run correctly after this adjustment, proceed
to the next step (2-2).
IMPORTANT : After adjusting carburettor according to the steps 2-2 and 2-3, the limiter plug(s) must be
installed on Idle and H mixture needle(s) hole(s) to comply with Emission Directive.
2-2 Presetting idle adjust screw, idle mixture needle and H mixture needle
1. Remove plugs from idle mixture needle hole (A)
and H mixture needle hole (B) using limiter plug tool
(C) as shown.
(1) Put limiter plug tool (C) on limiter plug in needle hole.
(2) Screw limiter plug tool anticlockwise 2 turns into limiter
plug.
(3) Pull out limiter plug tool with the limiter plug from
needle hole.
NOTE : When plug is damaged and left in the hole,
use needle or pin-shaped tool to scrape.
2. Turn idle mixture needle (D) and H mixture needle
(G) clockwise until lightly seated. And then turn out
both needles following turns.
Idle mixture needle : 2 H mixture needle : 2
3. Turn idle adjust screw (E) anticlockwise until its
tip just touches throttle plate (F). Then turn it in
clockwise 2 1/2 turns.

2-3 Adjusting carburettor
1. Start engine and warm it up alternating engine
speed between WOT and idle every 5 seconds for
1 minute.
2. Adjust idle mixture needle and obtain maximum
idle speed with 2.5 mm blade small screw driver.
3. Set idle speed to 3,500 r/min by turning idle adjust
screw.
4. Turn idle mixture needle anticlockwise to reduce
idle speed 500 to 750 r/min in the range of 2,750 to
3,000 r/min.
NOTE : Engine speed must be allowed to stabilize
a minimum of 20 seconds after each adjustment of
L mixture needle to assure accurate tachometer
readings.
5. Adjust H mixture needle and obtain maximum
WOT engine speed.
6. Turn H mixture needle anticlockwise to reduce
WOT engine speed 100 r/min.
7. Restart engine again and make sure engine runs
in the range of 2,700 to 3,200 r/min at idling and the
range of 9,500 to 11,500 r/min at WOT.Also make it
sure cutting device would not move at engine idle
speed and suitable acceleration.
8. After adjusting carburettor, insert and secure new
plug(s) (F) P005-001270 deep in the needle holes
per the Emission regulation using limiter plug tool (E).
NOTE : Initial carburettor setting (idle adjust screw,
idle and H mixture needles) shown on page 3 and 7
is to start the engine after restoration or carburettor
change. Idle adjust screw, idle and H needles turn
for designated engine revolution through procedures
indicated here may vary. As long as idle and WOT
engine speed is set in given range, variance would
be ignorable.
