Thanks Bondy your response helps alot.

I stripped back the wiring to its bare bones, so you are looking at less.

G'day prd, does this look OK to you? Its what I think it should be. You can add in the saftey switch later. Try to get it working first.

So, The heavy red wires are switched closed by the solenoid, when the ignition switch is turned to start. At ignition switch red wire is switched to yellow wire (white on your machine).

When ignition switch is turned to stop, the blue wires are switched together, this is earthing out the magneto, stopping spark.

Can you test to see if you have 12v at the ignition switch. 2nd image, brown looking wire.
If not is their a blown fuse in that wire. Is there power on any of the other wires?

Remove any unnecessary wiring, it just adds to the confusion.
