Went for a spin yesterday and after an hour of running sweet as you like it just cut out 3.5 miles from home bugger! No spark at plugs I had a spare rotor arm but still no luck. The points have been replaced with Powerspark electronic jiggerypokery so the plan today is to put the old points and coil back on and see how that goes. I have a multimeter but to be honest I'm dont really know how to use it properly Any suggestion are welcome.
