Thanks Silverbullet, Subydoug and Steptoe for your responses.
I have a few things to check out by the sounds!

Yes that white thing on the coil is the ballast resistor, and they don't go intermittent as far as I know. If they fail, they don't work at all.
As for you carbie problem, has it ever been rebuilt? Sounds like you must have some crap floating around in there blocking things up every now and then. I would suggest rebuilding it (easily done in a day, see my thread)
I don't currently have a multimeter with continuity, good to know about the ballast resistor.
As far as I know the carbie has never been rebuilt! I did take a look at your thread, doesn't look as intimidating as I had thought. It might be time to buy a kit.

Question, does the car stall for measurable durations, like 10s, or is it more like a savage miss? Does the engine sould lean at idle? Rich at idle? When the engine is running, if you get a hose and gently squirt water around the base of the carby and where the carby bolts to the manifold, it will stumble if there is a vac leak (only very little water is needed)
I will have to give this spray test a go. If there is a noticeable stumble might follow Silverbullets rebuild advice.
The car often stalls as the idle just drops right off, but it can be restarted very easily in most cases. It can be prevented from stalling by keeping the revs up. (making me think not a spark issue here?)
Im not entirely sure what a lean or a rich sound is like to be honest! It Idles quite smoothly I think. The miss can vary but is often not reflected in the digidash RPM gauge, quite quick and distinct.
It feels different from when I have had to use the cloth over carbie technique.

Ensure tank is empty so you can pull sender off and scrape out the crud from rusty insides of fuel line
I am almost at the bottom of my tank and am seriously considering dropping the tank and attempting a blow out of the fuel lines. In the car Hanes manual I have, it suggest washing the tank out with water - Is it just a matter of ensuring that it is completely dry before reinstalling the tank?
