Ignition Timing (Static)

Remove the distributor cap, adjust the contact breaker gap to
0.0l5" (0.4 mm.) and set the micro-adjuster to its mid-way
position. Turn the engine until No.1 piston is at T.D.C. on the
compression stroke (see "Top Dead Centre" page 61) and the
rotor arm points as shown on Fig. 98.
Mark the periphery of the pulley with a spot of white paint,
6.0 mm. to the left of the timing hole (viewed from the rear).
Turn the crankshaft in a running direction almost two complete
revolutions, until the white paint spot coincides with the tip of the
pointer. Slacken the distributor clamp plate and switch on the
ignition. Turn the distributor body slightly in either direction
until the contact breaker points are seen or heard to break.
Tighten the distributor clamp plate, switch off the ignition and
refit the distributor cap.
