Firstly, the ignition timing is done after setting the points gaps.You've gone wrong here:The gap setting and the ignition timing are entirely separate procedures so you need to set both gaps first by lining up one heel with the line on the points cam and setting the gap, then rotate the camshaft (by turning the crankshaft one full turn) and setting the other points gap. The points gaps should not then be altered.Once the points gaps are set then the scribed line has no further part to play in the setting of the ignition timing.Ignition timing is done by adjusting the backplate (for both sets) or each sub-plate as mentioned in your previous thread.The points gaps, therefore, cannot be set correctly or I think you are not following the correct procedure due to a misunderstanding of what the scribed line is used for.Also in order to set the ignition timing the points cam must be held/locked in the fully advanced position first.
