After being very proud of myself sorting out the distributor, the Ghia has now thrown another problem at me!
Over the last week or so the engine has been dying on me, usually when trying to start up. It'll turn and start fine but will stop running for a second or two, usually coming back to life again before completely stalling. After it's warmed up (if I manage to keep it running that long!) it'll perform OK, but occasionally do its dying trick whilst running. On Sunday it partially died when I was on 153 - the engine was running and pushing the accelerator did turn the engine more but without enough power to pick up speed. 10 seconds later and it came back to life again.
This morning it did it's trick a few times but then refused to start at all

I checked a few things quickly and here's what I've got so far:
- Electronic cut-out valve on the carb is working (if I plug/unplug the wire whilst the ignition on there's a definite and loud click)
- I put a timing light over spark plug wire #1 and there was NO strobe when I turned the engine on the starter.
- Ignition power appears to be getting to the coil OK
- Points are correctly making/breaking (tested resistance)
It looks like there's a problem with the high tension pwoer getting from the coil to the distributor - so my guess from all this is that either the coil or the condenser has failed.
Any further tests I can carry out to locate the problem?
Thanks all!
