Reading Plugs...

I'm trying to read my plugs, but i wanted some other opinons.

They look a little tan, but i think they are a on the white side, i don't know. Pretty much all the plugs look like this, and I had just been driving at cruise rpm prior to checking them.

Would you say to to jet the primaries up or down from here?

I'm thinking the jets in there are about right...

The plugs look good to me. Maybe slightly lean. How long were those in the car? They get easier to read with time.

they've been in the car for about.....9 months

but i just put a new carb on about a month ago.

i'll probably just leave the primaries alone, and tune the secondaries at the track.

Those plugs (if they all look like that), IMO, are just fine, no worries.
