3-3. Oil Pump Section (cont.)
ASSEMBLY
1) Fasten two M4x12 Pan head screws, first A then B so that Worm gear does not touch Oil pump. (Fig. 7)
2) Do not forget to set Flat washer 10 in place. (Fig. 7)
3) Install Oil pump cover and Worm gear, first Oil pump cover, then Worm gear.
4) After installation of Worm gear, make sure that Worm gear can be turned easily by hand.
3-4. Adjusting the Flow of Chain Oil
The flow of chain oil can be adjusted by turning the adjusting screw on the bottom of the machine using the slotted

INSPECTION OF PLUG CAP

1) Remove Plug cap from Spark plug. Then using circuit tester, check the
electrical conduction between Plug cap spring and the ground (earth)
terminal of Ignition coil complete. If the value of electrical resistance
is about 7k ohms, the conduction is normal. (Fig. 9)
2) If there is no or unstable electrical resistance, check if Plug cap spring
is properly connected with the ignition cable of Ignition coil complete.
Lubricate the inside of Plug cap using aerosol spray lubricant, and then
pull the ignition cable and Plug cap together spring out of Plug cap
using pliers. (Fig. 10)
3) Check if Plug cap spring is properly connected with the ignition cable.
If not, connect in the correct way as described below in 4).
Also check if Plug cap is cracked. If cracked, replace it by new one.
4) Install Plug cap spring on the ignition cable of Ignition coil complete
by piercing the needle portion of the spring in the center of the cable.
While taking care not to let Plug cap spring fall off the cable, grab the
cable with pliers and pull the spring back into Plug cap. (Fig. 11)
5) Check if Plug cap spring is properly connected with the ignition cable
of Ignition coil complete using circuit tester as described above in 1).
Defective connection can cause weak or no spark at Spark plug.
