   This unusual ignition seems reminiscent of the old hot tube ignition
which predated the Kettering ignition. The hot tube was externally heated
and the chamber inside held a bit of mixture that would burn and whoof! down
its length and set the main combustion chamber on fire.
   The timing was accomplished by screwing the tube in or out of the head to
advance or retard the timing by the path length of the flame. It was limited
in its effective rpm range. Later, in the Sixties I think, Kaehni made an
ignition that had all of the plugs wired to fire continuously and it too
worked after a fashion. I remember seeing it on a Buick-powered street rod
and Hot Rod Magazine affirmed that it worked but there was no follow-up as
to how well. It certainly looked good, thereby fulfilling most of the
requirement for a show car.
