Thanks for that Paul.
Right from the beginning i have just assumed the new electronic dizzy/coil supplied was ok but your comment/link has got me thinking that maybe there's a problem with the coil getting hot or may be a lower supply voltage when hot and cranking the engine over. I also have a high torque starter motor fitted which was second hand so maybe the starter motor draws more current when hot which in turns drops the supply voltage to the coil on a hot start up. This weekend i intend on doing a few checks with a muti meter on the ignition system.
One thing i have just found out today is the coil has a primary circuit reading of 1.0 omhs, i was always under the assumption a 12v coil with no ballast resistor had a primary winding resistance of 3.0 omhs and a 6v coil with ballast fitted had a primary resistance of 1.5 omhs so i am slightly concerned as to the 1.0 omhs reading. Have emailed the supplier to see what they say.
Food for thought and if any body can add to this then please do so.
