Re: CDI capacitive discharge ignition! what tha!?!
CDI's sometimes use an external electronic trigger, but never off of a points set that I know of.. 2 strokes don't need that kind of timing because they fire every revoloution....
the magneto creates a signal and power that the CDI can use, the CDI uses a capacitor and a resistor to time the energy transfered into the primary windings, then when it fully discharges, it collapses into the secondarys and sparks..
2 strokes don't even need any form of ignition box or timing system.. many chain saws and weed eaters just run off the magneto
