Air/Fuel mixture meter KS-1


Inside an internal combustion engine those same coloured flames are present though

not normally seen. With IKS-1 fitted, in place of a spark plug, the flame is

visible through the glass insulator and the fuel is ignited by a spark in the KS-1.

This allows the user to obtain greatest engine efficiency by assessing the colour and

appearance of the flame and correcting any faults thus revealed.

Using the product could hardly be easier, fit it into a warm engine, in place of a spark

plug, and you are ready to begin.

KS-1 gives you a fascinating insight to the working of an engine without the

usual complexities of most other diagnostic equipment. It can provide a unique view of

the behaviour of the fuel system, in the individual cylinders, which no other equipment

can do, saving in many cases time, expense and a great deal of effort in fault diagnosis.

A gas analyser gives an average reading of all cylinders, and no diagnosis of faults or

setting errors which affect mixture distribution.


The general appearance of the combustion flame when viewed through KS-1 is

as follows:


Yellow Indicates a fuel / air mixture which have excessive petrol content (rich).

Like a candle flame - producing more light but less heat.


Bunsen Blue Indicates a mixture which is correctly proportioned.


Whitish Blue Indicates a mixture which has less petrol content (lean)


Note: this colour is more easily seen at higher speeds.

At idle, engine instability and misfiring may occur before this weak

mixture and pale shade of blue is fully visible. Please place your vehicle in the shadow for better visibility of the flames.


Fitting KS-1 to the engine

1. Before fitting KS-1, start the engine and warm up to normal operating

temperatures, preferably by going for a short drive.

2. To assist with flame visibility, park your car in such a way that the engine is in the


3. Stop the engine, take care to avoid hot engine parts and brush away any grit from

around the spark plug before removing it. Remove the spark plug.

4. Fit the KS-1 in its place. Never over tighten KS-1 into the engine

as an adequate gas seal will be achieved even on taper seat applications with little

more than the equivalent of finger tightness. The rubber bush in a normal plug

spanner will not retain the KS-1 as the ceramic is smaller.

5. If the plug recess is not easily accessible it is wise to apply high melting point grease

to the KS-1 washer to help retain it.

6. Connect the spark plug lead of KS-1 to the plug cap of the car's ignition system.

The adaptor is designed to fit both types of plug cap (with bare thread or clip type

fitting) and fits most ignition systems. Try to keep the leads away from engine parts,

particularly the exhaust and rotating items.

7. Repeat the above steps if using more than one KS-1.

8. Start the engine. All cylinders should now be firing regularly and the combustion

flames should be clearly visible, either directly or in the mirror.

Avoid touching ignition parts when the engine is running remember ignition sparks can

jump, particularly if a connection is not secure.
