right all when I bought my Bobby, I really didn't use her at all now that she is nearly ready for the dredded MOT. I have been running her up etc. setting up timing, sorting out the emisions etc. Now the problem is when I let her warm up then turn her off she is very difficult to start I noticed that the coil was getting very hot and as time has gone by she is becoming more and more difficult to start. The other day the coil got so hot the coil has become disfigured and I was hearing a load of crackling which I presum means the coil has burnt out. now I have a spare mounted just for such a problem connected that one and bang she started straight away, but now that coil has been on there a while same symptoms seem to be coming back. so what I have done so far is checked the current going into the coil which reads 13.4V which I have read on the net that I must be running with a non ballast system, but both the coils the spare and the burnt out one are ballast coils which should be running on a regulated 9v so I am presuming that this is why they are burning out? or am I wrong? so the question is if this is causing the problem do I a) get a non Ballast coil or b) get a ballast in place?
and by the way it's running on a dual point distributer and yes the best would be to update the whole lot but funds are ight and I really can't afford that option.
