8.1.1 Valve setting procedure
Exhaust valve:
−
Turn crankshaft slowly with the starting
handle until the end of the compression
stroke.
In this position the exhaust valve
is closed (max. clearance between
rocker and valve) and the top dead
centre mark of the flywheel points
to the mark on the crankcase.
−
Check clearance between exhaust valve
and rocker with a feeler gauge and, if
necessary, set to 0.1 mm.
It must be possible to slide the
feeler gauge between the valve and
rocker without great force.
Inlet valve:
−
Turn crankshaft half a revolution from the
top dead centre mark in the direction of
rotation.
On engines with a closed flywheel housing
you can't see the timing marks
(O.T. = T.D.C.).
−
Take off rocker cover, turn engine till pis-
ton is in O.T. (T.D.C.) position.
−
Mark the position on the crank handle
support bearing
−
Turn engine with starting handle ¼ rota-
tion in engine rotation sense.
This makes the automatic decom-
pression ineffective.
Check clearance between intake valve and
rocker with a feeler gauge and, if necessary,
set to 0.1 mm.
It must be possible to slide the
feeler gauge between the valve and
rocker without great force.
