12. Seat square nut (G) in dent of handle grip and
push in corrugated tube (F) to the grip two or three
grooves from tube end.
13. Put together both grip halves.
14. Insert grip to handle aligning hole (K) with
holes on handle, and fasten grip with screw and
nut.
15. Connect throttle cable to carburetor. Connect
primary lead coupler and ground lead coupler.
1. Connect one probe of Ohm-meter or multimeter
to spark plug cap coil (A).
2. Connect the other probe to cylinder (B) to mea-
sure secondary coil resistance. Secondary coil
resistance should be in the range of 960 to 1,000 Ω.
3. I f t h e m e t e r r e a d i n g i n d i c a t e s i n fi n i t e
resi stance, remove spark plug cap and spark
plug cap coil, and measure resistance between the
conduction wire of high tension lead and ignition
coil core.
4. If the reading at step 2 or 3 is not in the range of
960 to 1,000 Ω, replace with a new ignition coil (Go
to "3-8 Replacing ignition coil").
