. mark on the gear cover are in line.. This should place the left hand
piston at the top of its compression stroke, the pOSition it must be in
to get proper valve adjustment for· the left hand cylinder. Clearances
are shown in the Table of Clearances herein. For each valve the thin-
ner gauge (minimum) should pass. freely between the valve stem and
valve tappet but the thicker gauge (maximum) should not. Refer to
the illustration, Valve Service,

needed to obtain the right clearance. The screw is self-locking and
will stay where set.
If valve clearance can no longer be held within given limits, replace
the valve.
To adjust the valves on the right hand cylinder,
. crank the engine over one complete revolution
and again line up the mark on the flywheel
and the "TC" mark on the gear cover. Then
