Hi Ian and JonE,
I have now tested the operability of the advance mechanism by twisting the spindle. This is easy to twist as you and JonE suggest it should be. On release of the spindle the weights spring back into place, almost touching.
When I twist the spindle I get about 2 degrees of free play and then 6 degrees moving the weights out. So this means that I am getting 6 degrees of advance at the spindle corresponding to 12 degrees at the crankshaft. The free play is resulting from the ovality in the holes in the supporting disc that I mentioned.
I can live with that for my purposes of cruising in my Ruby.
Regards
Graham.
