The ignition is transistorised with a magnetic pickup, so no points.

I'm now thinking that I shoud be setting the timing with no vacumm lines at 3000rpm and then checking at idle to see that it is 0 degrees with the advance/retard tubes connected, rather than setting at 0degrees.

If the advance/ retard mechanism is not working then this could mean that setting at idle gives the wrone point.
