distributor timing

[Ian Williams]

The other thing not mentioned and which makes quite a difference is the fuels available then and today, pre war pump fuels will have burnt at a different rate to modern fuels. Therefore notwithstanding wear and other variables old recommendations should only be considered a rough guide, this is also true for carb settings as specific gravity's of fuels have changed. On any seven TDC fully retarded will get the engine running, as others have said fine tune from there.
