McCabe-Thiele (Ted):
Can't imagine how a dowel gets broken - is the remnant in both halves or just the engine casing?
As it is part of centering the alternator I think it's important to find a fix.
Bryanj:
To test the field the green and white wires MUST be disconnected from loom or you are connected to griund via the green wire!

I replaced the coil mounting bolts with slightly shorter ones - shorting issue gone? Still need to do something to fix the damaged dowel hole issue though.
Replaced points with OEM units kindly supplied by Oddjob. points gap now set at 0.4mm and lined up (ish) with F marks using the original condensers. No spark ☹ï¸
Getting 12v at the coil black wires and also feeding the Hondaman unit black wire. Other wires connected correctly.
Anything else I can check? Ignition Coils seem to be ok BUT I refurbished them using the tips / tricks method on this site and I could have quite easily messed this up 😂
Oddjob:
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 coils and the points and see if they leak to earth, they shouldn't do.
After that report back.

Ok will try without Hondaman unit. But yes, I meant the black/white wires. Will double check continuity and connect points directly to coils yellow and blue wires.
I'm not feeding the coils black/white wires via the kill switch as I dont have one. I'm feeding 12v from the ignition output from an m.unit blue.
