Hi again,
I just noticed an error in my first post,the carb is a 28/36 DCD.
I don't know if the choice of carb,head and ignition are relevant to spark plug choice,but would rather get the best ones for the job.
Regards
JohnC |

I'd go for a standard one like a champion N9YC or example and see how it performs. In my Alfa I have had to put the hottest plug temp I could get to cut down deposits, but I only found out that they were the right plug by experimenting.

| For my fastback (high lift cam, twin webers and electronic ignition) I used standard grade Champion (N9YC?) and NGK (BP6ES I think) with no problems, though the NGKs seem to last longer and are a bit more reliable. |

Yes; I'd agree BP6ES' from NGK. They run a bit hotter & for Holbays used to stop them fouling up as much as the N9Y's. I think they have a different suffix now, but are still something like BP6's. Cheers. G. |
