The main control item in the Series Land Rover ignition system is the distributor. The distributor design causes the ignition timing to be advanced (i.e. the spark occurs earlier) as the engine speed increases. This is to allow the fuel sufficient time to burn fully. So the faster the engine revs the more advanced the timing of the spark becomes.
As with many classic vehicles, the timing on a Series Land Rover can also be advanced by a vacuum pipe connection to the inlet manifold - the higher the vacuum in the inlet manifold then the more the timing is advanced. Opening the throttle allows air into the inlet manifold and so lowers the vacuum. This reduction in vacuum causes less fuel to be 'pulled' through the carburettor and into the engine. So the reduced volume of fuel/air mixture is less compressed in the cylinders and burns more slowly. Hence the need to advance the spark timing.
At any particular engine speed there may be a combination of timing advance effects:
no throttle - high vacuum advance but low mechanical advance
full throttle - low vacuum advance but high mechanical advance


The March 2010 Australian homepage focusses on the properties and characteristics of spark plugs. Includes details regarding of their safe removal and replacement, together with advcie on what to inspect.

The Dec2010/Jan 2011 Australian homepage discribes what to do if the igniton light fails to light up when the ignition key is turned. A systematic diagnosis process is given as an aid to solving the problem.

The July 2010 Australian homepage discussed the connection between the operation of the contact points and the condenser in the distributor. The operation of each is described and how they work together to produce a smooth ignition sytem. Potentail problems are also outlined.

In February 2011 the Australian homepage addressed the issue of why the contact points need changing frequently. Possible causes and remedies are listed and a temporary solution suggested.

The June 2013 Australian homepage disccussed a range of possible problems that may occur with regarding the contact points. A remedy is suggested for each problem.

In July 2013 the Australian homepage describes the process required for setting the ignition timing on a Series Land Rover. Each type of ignition timing markings are covered and typical timings figures are given for a variety of Series Land Rover engines.
