Reasons.----From the factory the insulation of the leads is good. As the leads age the resistance to breaking down under load decreases.

Making the gap smaller allows the spark to jump at a LOWER voltage thus taking the strain off the leads.

Big gaps mean higher voltages and the spark quite often prefers to jump out of the side of the lead to the nearest earth point than across the one mil plug gap.

Higher revs make greater combustion chamber pressures. At higher revs with poor condition plugs the spark will track down inside the plug and not jump the gap and ignite the fuel.

Generally the need to reduce the gaps to get the fuel to fire is the first indication of spark lead problems or dying plugs.
