Post a pic of the broken dowel hole, is it in the crankcase or the casing? Remove the sprocket cover and make sure you haven't rushed any of the wires coming from the alternator against the crankcase, very easy to to this if you're not careful.
Isn't the coil feed wire black/white? as in coming from the kill switch? Disconnect the Hondaman unit until you get it running, don't add things that could be at fault, add them when you find the fault. Check the yellow and blue wires for continuity, make sure they haven't been broken or trapped. Disconnect them from the oils and the points and see if they leak to earth, they shouldn't do. After that report back.
Not a great diagram for what Dave doing,the revivalone is by far the easiest and simplist to follow. Dave are you just using the key to stop the engine then?
