RUNNING ADJUSTMENTS—Engine
The setting recommended above should be regarded as a starting point, as individual
engines may require more or less advance than this. Maximum power is obtained by
giving the greatest possible advance without causing pinking. Minor adjustments
can readily be made on the road.
To advance ignition turn the distributor body clockwise, and vice versa. Do not alter
the ignition more than 1° at a time (2° on flywheel).
To obtain top dead centre position turn the crankshaft until the small drilled hole in
the belt pulley is in line with the pointer attached to the timing cover.
The firing order is 1, 3, 4, 2 and the sparking plug leads should be attached to the
distributor as shown in Fig. 28. The cylinder numbers are counted in sequence. No.
1 being the cylinder nearest to the radiator.
Valve Timing
See page 5 for correct valve timing. To obtain top dead centre see above.
