Brain trust:
I know that on an M-14p with a Russian M9F magneto, timing on the prop is set at 14-16* BTDC. This translates to around 22-24* BTDC on the crank.
Assuming an M-14p motor with CD-5 (Chinese)magnetos stamped 25*, what is the proper angle on the prop BTDC?
According to Craig Payne’s chart for this configuration it suggests 8.8* BTDC on the crank and 5.8* BTDC on the prop. I don’t understand this figure.

It is not quite so simple – but the attached paper might help!

Very good document Richard, thanks!
Do you have such a document for the Chinese Housai?
Thanks,

I am afraid not precisely. Of course the CD-5 has internal advance like the M9-35M Russian magneto but I'm afraid at the weekend I simply don't know whether, like the Russian magneto, there are different "series" stamped onto the side of the magneto giving different degrees of advance. But I assume you have the Chinese maintenance manual which covers magneto timing in detail. If not please send us an email and we will send you the link to download the manual – this is a free service for anyone who could be interested. Richard.
