Adjustment
Remove the roeker cover and
turn
the engine crank with the aid of
the starting handle for half a revolution after the valve to be
adjusted has closed. It is easier to do this if the sparking plugs are
removed. This also provides an opportunity for inspecting
and
checking the sparking plug gaps.
Slacken the lock nut and adjust the rocker screw with a screwdriver
until the gauge is a sliding fit between the top of the valve stem and
the rocker face.
Now tighten the lock nut and check that the clearance has not
altered.

Premium grade fuels of
95
octane (research method) or higher must be
used for these engines, and with this fuel a
"
clean
"
engine will not
"
pink." However, with a substantial amount of carbon build up, it may
be necessary to retard the ignition slightly so that
"
pinking
"
is only
just audible when pulling hard with the engine speed above
1,500
r.p.m.
To advance ignition, rotate the knurled screw as indicated.
