To adjust the ignition timing:
1) Remove the spark plug from the cylinder head
and screw in the dial gauge, special tool #09931
- 00111.
2) Connect one of the lead wires of timing tester,
special tool 09900 27002, to the black wire
which is free near the fuse box and other one to
the ground as shown in the figure.

3) Find T.D.C, on the dial gauge by turning the
crankshaft slowly and then, set the needle to
"0" position.
4) Turn the crankshaft slowly clockwise, i.e., re­
verse direttion of engine rotation, and stop the
crankshaft being turned where the sound of the
timing tester fades.
5) Read the indication of dial gauge. This indica­
tion shows the ignition timing in piston travel
from T.D.C.

The magneto is originally set so that the correct
i
gn
ition timing point can usually be obtained by
only adjusting the contact point gap within the
range of 0.3 "' 0.4 mm. However, if the magneto
base is removed or the point is renewed, the rela­
tive positions between the base, point and crank­
case. may change and they require re-adjustment of
the magneto base, in this case, adjust the base as
shown in the figure.
