I have a very cold-blooded MKII.
2.4L, twin Solex.

In the process of cleaning and checking, I find the last maintainer
installed Champion RN9YC plugs.
They are supposed to have N-5's.
I have some N-5's in hand, looking at the porcelain on the 9's they
sure look white.
Not used to that!

I can drop N-5's into it, but what is that going to do for my cold
drivability?

Holding off for now.

Thanks!
