Dklude, glad you like it.
Paraflyer17, no problem, have a look at the photo below. The black wire on the right connected to the carb mounting bolt, is the new earth point, and the blue wire on the left, is a second connection to the low tension coil terminal.
The new kill switch on the panel (earlier photo) is either open circuit in the on position, and just runs the coil lead to earth in the off position. (Same as the throttle kill switch).
I used a 2 position switch rather than a spring return switch, so that in an emergency, I can just flick the switch to off, rather than have to hold it against the spring until the engine dies. I guess I'd have other stuff to concentrate on at such a time.
Hope that helps.
Mark.
