OK we are up and running now. This has been very strange. I have checked everything, valve timing. Static timing, spark ugs, leads,carbs.. In the end I checked the voltage on the ballast wire under load, it was only 4v. Can't understand why it wouldn't start with 12v supplied straight to it unless it was flooded. Anyway I have now fitted a lucas 12v sports coil and bypassed the ballast wire and all seems good. Unable to road test at the moment with this weather.
The other strange thing it the fuel and temp gauge stopped working which is because the solid state voltage regulator is fried, its only putting out 2v. Fitted the original and the gauges work, so ordered a new solid state one.
Seems strange that both these problems are all linked to the ignition wires.
Its booked in for a rolling road tune at the end of the month.
