Thanks Tyler.
The kill wires don't work. I have to stop it either by switching the fuel off or pulling the plug lead off. It used to work but I think a rubber bit has come adrift as the wires wont touch now.
The ramp in the cam in the carb despite going to full lift to bring the wires together doesn't get them to touch and short out.
I agree about the throttle position but checking cam position against the throttle everything lines up, particularly the kill cam ramp, which is fully "up" when throttle in uppermost position.
