The most common thing that most young or inexperienced moped mechanics struggle with is the machines electrical and ignition system.  Most systems are actually very simple and crude by todays technology standards. Often times people tend to over-complicate and over-think things when trying to diagnose their machine’s inability to run or function properly.  As a rule, 99.9% of  mopeds that don’t fire/get spark are not due to a faulty secondary HT coil (the one with the spark plug wire attached to it).  Also on that same note, electrical components usually break-down from either corrosion or heat or physical damage…in other words, usually, they don’t just break for no reason. The ignition parts that will most likely be the root of your inability to get a spark will either be in the contact points or the ignition switch/wiring.
