Failing iridium plugs.
I think it’s been on here before but it still seems to be a problem without an obvious explanation. It's a mystery.
Iridium plugs sometimes seem to ‘die’ once they get ‘wetted’ by carbs/injectors that supply an over-rich mixture.
(Please note - this isn't about plugs that get heavily 'oiled'.)
This doesn’t seem to happen with conventional plugs but seems to happen at times in very different engines with iridium plugs.
It’s not just that they sometimes fail when they are ‘wet’ but don't work after they have been ‘wetted’ like this.
Has anyone a reliable, sound, convincing, scientific, plausible, sensible explanation for this – ‘cos I can’t think of one!!
Please resist offering hairbrained theories!!!
