latest news!! the cut-off switch has left this mortal coil...so l've installed a spst rocker switch. l cut a hole in the shroud where it seemed it would fit, yep, it didn't fit - so mounted it above the carb on a piece of alu angle (and glued a piece of plastic over the hole l made). Works fine.
Just to re-iterate, these are a piece of sh!t, don't buy one
