Two Stroke Engine Ignition systems

Solid-state ignition modules behave like light bulbs. That is, they usually work fine until complete failure. Old-time magnetos often failed by degrees as contact points oxidized and became resistive. As pointed out in the previous chapter, open sparks and a gasoline engine are not a good combination. Some gasoline vapor will be present, especially if [...]

Any small-engine ignition, even the most primitive Wico magneto, can generate the 12 kV needed to fire a clean spark plug. But none of these systems deliver the voltage needed to fire dirty plugs or ignite less-than-optimum airfuel mixtures. This is why small engines are so susceptible to flooding and why spark plugs need such [...]
