The carbon brush wears and you get the sooty material. You said (in your previous message) you replaced the plug leads you should replace the cap and the rotor arm. Whilst you are at it, when were the conventional points replaced. I seem to remember me replacing them (the points) every couple of years. For the work that was involved it was not worth reseting the old ones ... which always got pitted and thus could not be set accurately. I think you should replace all 3 components. They are cheap enough. Regards Charles -- Please remove _removeme_ to reply. Work: Hobby:
