Using a wrench on the starter clutch bolt [A], turn the
crankshaft clockwise until the line [B] (TDC mark for #1,4
pistons) on the starter clutch is aligned with the notch [C]
in the edge of the timing inspection hole [D] in the starter
clutch cover.
CAUTION
The crankshaft may be turned while the camshafts
are removed. Always pull the chain taut while turn-
