Thanks all.

I will check the spark and timing, although it started and ran like a champ when it wasn't hot.

I shall check the fuel pressure tomorrow.

I rebuilt the trigger points, but will check that again..is temperature likely to affect them?

Starter works fine, all ok in that regard. The car is behaving very differently when hot...I shall see if I have the shop manual troubleshooting guide.

It was quite amazing to drive it..it is incredibly serene and beautifully damped..it fair glides along the bumpy Cornish roads. I've got so much money in it I will have to sell it, but if I drive it any more I can tell I am going to get addicted to it..
