G'day,
there is an insidious fault with old dizzys with action plates, the moving plate attached to the vac advance module. Ancient dizzys had a proper earthing strap from this plate to the dizzy body, more modern penny pinching versions did away with this strap. Result - devious misfiring due to faulty earthing via dirty sliding contacts.
cheers,
Bob
