I'm still having trouble with the timing on my G3C, probably because I haven't adjusted it again yet
Found this in a WC Haycraft book, don't know why the 1964-6 bikes went metric.
How on earth do you measure 10.98mm before? I'd have trouble getting it spot on if were a straight 11mm!

Welcome to the Forums!
See page 32 in the Workshop Manual here:

It gives the figures, dependant upon engine number. If yours has a manual A/R mag (i.e. without ATC) don't use the 'Retarded' figure. Always check/set the points gap before adjusting the timing. If it does have ATC the mechanism can stick so check that it's operating freely and the weights return to the Retarded position when the engine is stopped. The 'Return' springs can also be weak. (I'm not sure about the 'C' competition models but I don't think ATC was fitted on them because when used for trials the riders like to be able to adjust the timing manually according to the demands of the particular section on the course.
