Eating Plugs

[Bilko]

What would cause this?

Second plug in a fortnight

Pissed off, from Belfast

[mark]

whats the colour like ? what sort of plug?
mine was eating them before the piston shrunk and it siezed due to running a b9 with 17 .5 degree timing and rich as fook on idle to 1/2 throttle , hopefully be fixed when/if i ever get it back

Hi there,
Plug gap and temp can be critical on a tuned motor, On my tuned 225 Rapido, ignition set at 17' i run a Champion N3c with the gap set at 0.5mm.
What is actually happening to the plugs? any pictures.

Cheers.

I wrote the post on the move so didn't post much detail, but the plug is NGK B9ES gap is .5. Plug looks great. Dark coloured. I've gone through a new B9ES and an old B8ES Not from the same place. One English one from Northern Ireland.

Rob, there's been a spate of counterfeit NGK plugs about. I'd change to Nippon Denso from MB if I were you

[Bilko]

I was thinking of trying another make, but I'll see if it's not another issue.

Thanks for the info.

The Nippon Denso Iridium in my Muggy is into its 3rd Year (about 2.5K per year)and 2 years on the Imola, (Same sort of mileage so nothing compared with some) I have never had to change them and rarely carry a spare, I was always changing the NGK ones
