Pull green wire from cdi to loom see if that cures it.

Check alignment of pick up and trigger magnets, use some tippex.

Make sure al connections are sound at the stator (soldered) and the terminals to the cdi.

Also Check the resistance from the engine case back to the cdi earth wire if it's too high it create's a weak spark
