1929 ignition control

Unknown

I am now almost done restauring my 1929 Std Sedan. Only missing a few minor details.

And yesterday, after having been asleep for almost 50 years, the engine was fired up for the very first time. Fantastic feeling:-) And it runs great.

One question: the inginition control on the steering wheel runs very easy with almost no resistance, wherefore it easily can move unintended. There does not seem to be any return spring or similar built into the system, correct?? What secures the ignition control lever to stay in position??

Thanks /gert
