A week after saying that the plugs in my old Escort have been in there without trouble for years without trouble and the last couple of times I've started it I've had to add in a bit of throttle before it would catch.
A quick check shows the HT leads are OK, the timing is still fine and there's nothing wrong with the distributor.
The plug ends look fine and there's still a spark, but it looked a bit weak.
I guess my first fix will be to change the plugs.
Ah well.
