My KZ2 uses a RB magneto for ignition. I have seen too many vintage cars stopped on the side of the road with magneto failure, even after the owners have spent hundreds of dollars getting them reconditioned.
I like having my cars 100% oauthentic but they need to be reliable as well. My brother is restoring a 1914 Fiat Tipo Zero and he also wants the car to be correct but trouble free, so we have been thinking how to keep the right look but make them better.
A magneto is really just a distributor which makes it's own HT spark. Could we find a way to feed spark in to the distributor part of the magneto from a coil hidden out of sight somewhere?

Here are two magnetos. the one on the left is the one which will go in the car, the one on the right is the spare. Note the brass fitting on top of the locator peg on the magneto i am going to use





This is the magneto I am using. The magnets have been removed and replaced with a steel cover so it no longer generates any spark, but the armature has been kept to provide drag for the automatic advance to work correctly





The top peg is the original. The bottom one is the new one my brother has made with the fitting for the coil lead to feed the spark to the distributor part of the mag.




It works perfectly on the bench, firing four spark plugs in a dummy cylinder head so we are confident it will work on the car. I will let you know when the motor is running!

La magnéto est tout aussi fiable que les autres systèmes, voire + car elle est indépendante du système électrique général

Tous les avions à pistons utilisent la magnéto, ce n'est pas sans raison.

NB: mon anglais n'est pas au niveau me permettant de le dire dans cette langue, merci à un traducteur bénévole et compétent

The magneto is at least as reliable as other systems, or even more, since it is independent from the overall électrical system of the car.
All piston-equipped planes still use a magneto ; there is a reason.

A magneto does throw a stronger spark, but there is also a reason why piston engined aircraft run TWO magnetos!.

Juste un petit trou
Ceci fait un peu désordre. 
Vu que j'ai une autre magneto,  je vais repasser en allumage d'origine.
