Thanks for going to the trouble and expense to take one apart. I replied to your post but it hasn't come up yet? Also tried to put a couple of pics on the mc-engine group and it kept giving me problems. I finally got one of them to post under the file Swiss. It is of the small CDI coil that I modified for direct mount on the plug. It works well and is light enough that it doesn't require a separate mount.
