I can obviuosly confirm the dwell with a dwell tach. Would a first course of examination be to set the points to give the desired dwell regardless of whether the gap matches the factory setting or not?

Adjusting the points gap is a crude way of getting the dwell right. It may be that the 'correct' gap gives an incorrect dwell on a worn dizzie.
The poor spark might also be related to wear, or could be the usual causes of wires, plugs etc.
Depending on the type of electronic conversion, this may stop the wear affecting the dwell angle, but in extreme cases the spindle jigging about will affect the HT as the rotor moves around relative to the cap.
