This does seem to work as a cut off stopping the spark when connected to ground.
I have also re checked the rotary valve. this was still a bit out. I have re done it and hope it is now just about right. the bike now splutters along a bit and sort of runs.
the carb is next on the list for a recheck. Does anyone know "roughly" where to time the stator in the adjustment slot ?

Hi I have sort of got around the problem by buying a running bike :-)
I will now start swapping things over to find the problem.
