Sounds like there is an issue in the pre-heating system (glow plugs). It might just need a new set of glow plugs or it could be the timer or various other things, do you have a workshop manual?

It sounds like glow plugs to me. Mine had the same problem, turns out that the tips of the plugsa had blown out, they were the cheap plugs from ebay.

if it happened suddenly it's probably not the plugs, but the timer/relay/fuse or a wire somewhere. I think the timer and relay are one unit.

if the plugs are original they could probably do with replacing anyway

edit - It may also be at the back of the motor on no.6 plug. there is a metal bridge that comes across the manifold (i think from memory) I remember on my 60 this had corroded somewhat. I cleaned it up and put it back on but there wasn't much left of it. (still worked though) There is also a plastic bung thing that had melted.
