2 CARBURETTOR ADJUSTMENT PROCEDURE
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/
FD” 2-stroke oil.
6. The recommended bar and chain must be installed, and properly tensioned.
NOTE : When the carburettor is changed with new
one, pass the fuel through fuel line pumping
primer (A) several times, and leave the unit for
one hour to dunk the carburettor diaphragm for
stable fuctioning before operating engine.
NOTE : In order to achieve proper carburettor adjustment, a 30, 35 or 40 cm bar and chain combination
should be installed on the unit, otherwise serious engine damage will occur due to overspeeding.
B. Preliminary adjustment. Adjustment by Idle adjust screw of carburetor.
Start and run engine for 100 seconds alternating engine speed between WOT and idle every 5 seconds.
Adjust idle adjust screw to 3,200 +/- 200 r/min. Make sure WOT engine speed in range 12,500 - 13,100
r/min. If engine does not run correctly after this adjustment, proceed to the next step 2-2.
2-2 Presetting Idle adjust screw, L mixture needle and H mixture needle
Tools Required : Small screwdriver with 2.5 mm
blade, P/N G310-000050 electronic tachometer,
P/N Y089-000091 D-shaped tool (A).
1. Turn L and H mixture needle clockwise until
lightly seated, and then turn out both mixture nee-
dles following turns.
L mixture needle (B) : 1 1/2
H mixture needle (C) : 2 1/8
NOTE : If needles are overtightened during seat-
ing, damage to carburettor may occur.
2. Remove air cleaner lid to expose the Idle adjust
screw and throttle plate. Turn Idle adjust screw (D)
anticlockwise until Idle adjust screw tip just touch-
es throttle plate. Then turn it clockwise 1 1/8 turns.
Reinstall air cleaner lid.
NOTE : The initial carburettor settings for Idle ad-
just screw, Idle and H mixture needles are intended
to start and run the engine before final carburettor
adjustments are made through this procedure. The
actual number of turns needed for engine opera-
tion may vary.

2-3 Adjusting carburettor
1. Start and warm engine for 1 minute alternating
engine speed between WOT and idle every 5 sec-
onds. Turn H mixture needle (C) anticlockwise until
engine speed drops to approx. 12,000 r/min at WOT.
NOTE : Do not run engine at high speed without
load longer than 10 seconds, or engine damage
may occur.
2. Adjust L mixture needle (B) using D-shaped tool
(A) to reach maximum engine speed just before
lean drop off.
3. Set idle engine speed to 3,900 r/min by turning Idle adjust screw
(D) . Engine speed should be stable
at 3,900 +/- 50 r/min after Idle adjust screw adjustment.
4. Turn L mixture needle
(B) anticlockwise reducing engine idle speed 700 r/min to set idle speed at 3,200
r/min. The engine idle speed ranges 3,100 - 3,300 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.
Before adjustment, WOT engine speed should be 12,000 r/min or less. If engine speed is higher, turn
H mixture needle
(C) anticlockwise until 12,000 r/min is achieved. To make the final WOT engine speed
adjustment, turn H mixture needle
(C) clockwise in 1/8 turn increments with the engine at idle, then
squeeze throttle trigger and check WOT engine speed. The final WOT engine speed should fall within
12,600 - 13,000 r/min range.
6. Start engine, and verify engine idle speed ranges from 2,800 to 3,600 r/min, and WOT engine speed
ranges from 12,500 to 13,100 r/min. Make sure the chain does not rotate when engine is idling. When
final adjustment is completed, the engine should idle, accelerate smoothly, and attain WOT per above
specifications.
NOTE: Engine WOT, and idle engine speed in field operation may vary from final adjustment specifica-
tions due to changing ambient conditions, fuel, and engine loads. Safe engine speed variances should be
within the WOT, Idle engine speed ranges listed in Section 1-2, otherwise the carburettor should be read-
justed.
