Details make the difference. It might be a somewhat overused saying, but it is undeniably true in karting. That’s because the mechanical side is as basic as possible and only includes that which is strictly necessary; because performance is very close and leaves no room for error; because an apparently minor setback can affect an entire weekend. So, perhaps during a race in which everything seems to be going smoothly, an unexpected episode can change the situation and spoil all the hard work. It’s usually called "bad luck". However, that’s only partly true, because with a little more care and a few little tricks, you can avoid several "unfortunate" setbacks, and understand that, sometimes, rather than the preparation of the engine, it is a tape or a clip that cost a fraction of a Euro that make the difference.
