CHECKING THE IGNITION TIMING
A timing light is required for measuring the ignition point. It must be connected between the ignition coil and
spark plug of the number 1 cylinder. For the check, the ignition coil must be unscrewed from the bracket
of the number 1 plug. The removed coil is then connected, using a spare ignition cable to the spark plug,
the timing light can then be attached to this cable.
NOTE: A conventional spark plug HT lead is required for this test.
The firing point is 8° ± 2° BTDC at an idle speed of 750
+ 50
rpm.
