How often to run the engine in a Centurion?

[MartinCummins]

Thanks, Phil, for your kind words. Still, off topic, my Father remembered, as a very young child, around 1905, a French mechanic coming from the manufacturer of his Father's car (Either a Mors or a Darracq) and staying with the family while he updated the ignition from Flame to Electric. This took around a week, and said Frenchman managed to set fire to himself while brazing. As a young child, father was much impressed by the mechanic calmly throwing himself into the nearby horsetrough, and continuing the modification, somewhat bedraggled! True!
