Reply to "Are Pertronix and Magnaspark"

In that they have electronic sensors instead of points and condenser, yes. Magnaspark II is centrifugal advance, while Pertronix offers a vacuum+centrifugal option. My Speedster was equipped with a Magnaspark II when I bought it, and had terrible off-idle stumble and low end performance. When I replaced it with a Pertonix SVDA distributor, the difference was night and day. Distributor advance needs to react to both throttle position and engine RPM to be effective, IMO.
