wired like this. I was imprecise. And yes about 'slow' ignition but I tried with more advance and it does not fix the problem, only makes engine run with a harder note to it. More power but somehow I thought engine sounded slightly unhappy and backed off until it started purring. If you understand. It appears I need to look elsewhere, it is not the timing map (I tried everything there); how big a difference measured by seat of pants does it make to time cams later ?
