Dear Friends,

Does anyone of you know about the required advance in ignition for the
1595CC LR engine?

The engine I am currently rebuilding doesn’t have the original DVXH4A type
distributor any more.
Because I can’t get the original distributor, I need to stay with the later
Lucas 25D type. As most Lucas distributors the maximum advance and the curve
in which the advance occurs, can be tuned. It is the result of the cam and
springs used. You will find an excellent article explaining this at:
www.teglerizer.com/mgstuff/lucastuning.pdf

The question is what advance in what curve does the 1595cc engine require?
The only data I can find is in the workshop manual: static advance of 15
degree (page A-12, Operation A/64, distributor and ignition timing).

The current Lucas 25D on my 1595CC engine comes from an 1100 CC A-engine
used in mini’s, build somewhere in the ’60.
According to the used components it gives a maximum advance of 32 degrees.
Which, in combination with the static 15 degrees comes on a maximum of 47
degrees before TDC. To me this seems rather much. But I am not sure.

Retuning the Lucas distributor is rather simple

Do you have a clue or further information?

I will be pleased to hear from you.
