Checking and adjusting the
ignition timing «fixed advance»
(fig. 32)
Inspection
•
remove the rubber cap which seals the inspec-
tion hole on the R/H side of the reducer box oppo-
site the flywheel;
•
to find the exact moment when points «A» and
ccB .. (fig. 31) start opening, it is advisable to use an
appropriate timing light to be set up between the
breaker feeding clamp and the ground.
Timing the right cylinder (fig. 32)
•
turn the flywheel counterclockwise (Le. engine
rotation) until the piston is at the end of its com-
pression stroke (both valves closed).
At this stage, mark CCO» on the flywheel (TOC for
right cylinder) should coincide with mark cc1» on
the inspection hole rim;
•
turn the flywheel clockwise until mark cc2» on
the flywheel (fixed advance) coincides exactly with
mark cc1 .. on the inspection hole rim.
At this point, contact breaker points ccA» should
start to open (ccA)) fig. 31).
Timing the left cylinder (fig. 32)
•
turn the flywheel in the normal sense of rotation
45
of the engine (anticlockwise) until the piston is at
the end of its compression stroke (valves fully
closed)
.
At this point mark (cS
))
on the flywheel (TOC of left
cylinder) should coincide with mark
c
c 1 )) on the in-
spection hole rim.
