SPARK PLUGCheck the plug gap and replace if the limit is exceeded.
Standard value:
1.0-l .l mm (.039-.043 in.)
Limit: 1.3 mm
(.051 in.)
Caution
1.Do not attempt to adjust the gap of the platinum plug.
2.Cleaning of the platinum plug may damage the plati-num tip. Therefore, if carbon deposits must be re-
moved, use a plug cleaner and complete cleaning with-
in 20 seconds for protection of the electrode. Do not
use wire brushes.

IGNITION POWER TRANSISTOR
NOTE
An analog-type circuit tester should be used.No. l-No. 4 coil side
(1)Connect the negative (-) terminal of the 1.5 V power supply
to terminal (4) of the ignition power transistor; then check
whether there is continuity between terminal (13) and termi-nal (4) when terminal (3) and the positive
(+) terminal
are connected and disconnected.NOTE
Connect the (-) probe of the circuit tester to terminal (13).
