I still don't understand why a magneto ignitions aren't developed with an advance mechanism for street vehicles. I already said that I understand that race applications probably don't need an advance since they aren't doing a lot of stop and go like vehicles in traffic.
None of the reading I've done about magnetos suggests that their design precludes an advance mechanism. I've read people's explanations for the lack of an advance that ranged from "it would cost more to make" to "It's made to be a simple as possible". I still don't see why a manufacturer in the modern technological era, wouldn't modify their magneto to have an advance function to make their magneto ignition an even more appealing choice for street vehicles.
... it seems to me, that there has to be some mechanical reason inherent to magneto design why they don't do it...
*******When My Dad learned to drive as a kid, he learned on a car that had an advance lever on the steering wheel, so as the engine went faster you advanced the spark. You also retarded the spark to start the car... This advancing of the spark timing was all replaced by the invention of distributors that automatically advanced and retarded through centrifugal force and also vacuum.
It just doesn't make any sense to me that the most popular magnetos made today have no advance mechanism, and more to the point, that there's no mechanical reason which precludes them from developing an advance feature to improve it's street-ability, yet these manufacturers don't persue what seems like an easy avenue of improvement...
Come on, seriously,... Why don't they commonly have an advance... ???
