What is most suitable to check spark plug gap?
A feeler gauge is made up of a collection of calibrated metal strips of varying thicknesses. The blades look like a pocket knife when joined together. It’s the best tool for measuring and adjusting the spark plug spacing.

What should the spark plug gap be on an old car?
The rule of thumb for the spark plug gap on older engines is coil ignition 0.025 thou and magneto ignition 0.018 – 0.020 thou.
What’s the difference between ground and centre spark plugs?
In order for a spark plug to work as it should, the gap between the ground and centre electrodes needs to be perfectly calibrated. By adjusting this distance you are sad to be ‘gapping your spark plugs’. With the aid of a feeler gauge and the following advice, this adjustment is certainly something that you can do yourself.
What are the main issues with spark plug settings?
What are the main issues with spark plug gap settings? 1 narrow-gap risk: spark might be too weak/small to ignite fuel; 2 narrow-gap benefit: plug always fires on each cycle; 3 wide-gap risk: plug might not fire, or miss at high speeds; 4 wide-gap benefit: spark is strong for a clean burn.
Do you need to adjust the gap on spark plugs?
While plugs are pre-gapped from the factory, the gap may need to be adjusted for the vehicle that the spark plug is intended for. Those with modified engines must remember that higher compression or forced induction will typically require a smaller gap setting (to ensure ignitability under higher pressure).
Can a spark plug be open to the intake valve?
While most engines like the spark plug’s gap open to the intake valve, there are still other combinations that make more power with the gap pointed toward the exhaust valve. In any case, engines with indexed spark plugs will typically make only a few more horsepower, typically less than 1% of total engine output.
