I checked that, but this would not have given the same symptoms, as far as I can see.

To summarise, the original problem was a vacuum leak due to a split PCV diaphragm. After I had located this and temporarily removed the PCV unit until I get a new diaphragm (Fred Smith has them, one on its way), the further problem turned out to be due to loose screws in the carburetter, my fault as I had pulled it to bits looking for the problem when I was in town. But looking for that I gave the whole ignition system a thorough going over.

It is now running much better than it has been for some time, probably because the diaphragm has been leaking for some time (there were actually four splits).
