Given that it can sometimes be difficult to tighten the magneto drive up with out it slipping and loosing the timing, would anyone like to speculate on how accurate the factory timing was? Would it have be done absolutely dead on, or do think that near enough was good enough? I wondered about that because of production line constraints. It was common practice in the Midlands for workers to be employed on piece work rates so obviously numbers produced would be the dominating factor. Not a system conducive to absolute accuracy I would have thought.
