A wide gap creates a longer spark arc but without sufficient "juice" from your ignition system, (including amps), can be weak. A small intense spark is MUCH better than a big, weak spark, especially when dealing with richer fuel mixtures and more volumes of fuel being burned.

OHHHHH, Awesome thanks, much appreciated brother!!
