Hi David
You mentioned HT leads melting dispite 70c temp reading.
I know the first surgestion will not help the over heating,
but check your gauge by puting the capillary builb in a
electric kettle and bring to the boil, if you have a
thermometer to check results the better.
My second is check the rad tubes, see if you can see the
entry to the top of the tubes. After older engine re-bulds
the rust and lime stone scale loosens and the pump flushes
it out up the top hose, have a goodlook with a torch mirror
on a stick/or inspection video camera. If the tubes look bad
try reverse flushing the rad.
