semple checks like what colour are the plugs which would give an indication of mixture, (as does the colour of the tail pipes).
If there is nothing very obvious then a systematic check of ignition timing, carburettor settings is the way to go (Coil polarity is another that can weaken the spark, negative terminal to the distributor (white\black cable). A compression check is always worth while also if you have the means to do that?
If you still have the AED fitted and it isn't woking correctly, giving an over rich mixture, it will dilute the oil to such an extent there is very little oil pressure. I changed the oil and filter and the pressure returned to an acceptable level. Junked the AED completely and put on a manual choke, one of the best things I have done to the car.
What I would be most concerned about is running it with little oil pressure. This is one quick way to knock the crank out. I discussed this with a very experienced mechanic who worked on these cars "back in the day" and confirmed this. If you have low oil pressure then I would sort this out first.
If you think it is the fuel / oil pressure cut out switch then you can disconnect the lead from it, connect it to earth, and the pumps will run continuously. If the cutting out then stops you have found the problem.
Another thing that happened to me was the low tension wire from the points broke internally. Looked fine from the outside but the conductor inside was making intermittent connection and giving all sorts of weird running problems.
Hope this helps.
