right just been out and investigates further. My ht leads were on different to above diagram.
I have now refitted them exactly as the diadgram shows.
I also took the rocker cover off to see if there was any damage inside the head that was visible but nothing at all.
I then put £5 worth of optimax in her as fuel needle was very low
also cleaned the dizzy cap with cloth and plug connection to the dizzy itself
I have tried starting her up now after all this, but she just keeps cranking over now and won't fire at all or run.
HELP PLEASE!
