Hi Phil
Have you manaed to find the culprit.I have exactly the same problem.I have also had my fuel system checked,as well as the carbs reset,but to no avail.I have also replaced the fuel pump from 0.25bar,to a 0.5bar.
My car drives ok for a while and then starts to surge( fuel starvation) .i was at a show and on the way back i had to physically stop,and then pull off again, where the car would drive ok for a short distance and then the same trouble starts again.You will agree it is very frustrating.One of my mechs indicated that i need to replace the advance / retard unit,unforunately theses are hard to find in RSA.Do you think this may have something to do with it? If i rev the motor when she is stationary it revs fine,however once the motor is under load she then has the symptoms.I have also drilled a little hole in the fuel filler cap to see if it is vaccum related,to no avail.I now don't know what to do or where to look,as all the obvious culprits have been re-looked at.I have been struggling with this since feb 2010, so you now know my frustration.
Hoping you / someone has a solution.Regards
