Maybe the spark plug needs replacing.


No, it`s not the spark plug unfortunately.(Already changed)

There`s no spark arriving on the spark plug lead ( proved by using a
neon timing light tester )

Thanks anyway


This is the point I give up, and send it in.

Unless its a simple broken plug lead?

If it wasn't electronic, I would say it was the contact breaker or
capacitor. I've no idea what replaces these in an electronic magneto,
but it probably isn't repairable other than by a new electronic unit.
Another possibility is moisture has got into the HV coil and the
insulation broken down, but they are usually pretty well waterproofed.
