6 cylinder running rough but....

[poppyman]

Just had another thought, a mate had similar problems with his stag. We replaced everything and it still had the problem   So he bought a new electronic ignition as that was the only thing not changed, part way through stripping the dizzy we found the earth wire was broken...... It did'nt look broken untill it was moved... so it was making and breaking contact. New wire fitted, problem gone  It's very easy to miss.

This little braided cotton covered wire is a master at looking ok but inside its broken 

Its been a misfire or wont start factor for many years

on some the wire is fixed to the base plate  nothing stopping you making up a replacement , best if its silicon sleeved

As this remains flexible and doesnt get cooked by the heat  always keep a loop to allow the movement of the vac unit rotating the base plate
