spark plug gap

Gapping The tools and methods used to set spark plug gaps vary greatly.

The higher voltage allows larger spark plug gaps for added power, smoother response and better fuel economy.

Important factors are the timing of the spark, the correct heat range and the correct spark plug gap.

Incorrect spark plug gap setting.

He was now ready to start it up to ensure that it was running properly and the spark plug gap was correct.

This results in a current flowing in the spark plug gap (without resulting in a spark).

If the contamination is bad enough, it will bleed off so much voltage that it never reaches the intensity to jump the spark plug gap.

The HEI system produces a more powerful spark, which allows for a wider spark plug gap.

However, when the voltage builds up sufficiently, it will jump both the the intensifier and spark plug gaps, creating a good spark of long duration.

The spark across the spark plug's electrodes forms a small kernel of flame approximately the size of the spark plug gap.

You know how you can never remember all those little bits of information like tyre pressures, spark plug gaps and how much oil (and what type) goes in where?

A spark plug gap gauge is a disc with a sloping edge, or with round wires of precise diameters, and is used to measure the gap.

The coil was basically a transformer to step up the low battery voltage (6 or 12 V) to the high ignition voltage required to jump a spark plug gap.

To test properly the mechanic removes the plug and lays it against the engine so that the base around the plug is electrically grounded, kicks the starter lever and watches the spark plug gap for a blue spark.
