Google "reading spark plugs with unleaded fuel."

The paraphrase is that unleaded fuel burns cleaner and leaves less deposits so plugs are harder to read.

In any case, the OP has lots of work to do before he can even worry about reading plugs.

My plugs look like pictures 4-5-6 but keep in mind, my car rides in a trailer most of the time unless I'm going to something local. I have perhaps 100 miles on my plugs in the last year...

Did more carb tuning to make car more rich and found where header leak is which affects plug#2 and #3 I believe. Im happy its not too lean anymore. Now I am going to fix header leak then check valves.

Plug#1

plug#2

plug#3

plug#4

plug#5

plug#6

What exactly did you do to the carbs

Looking at the picture above there's something wrong with the carbs or the intake must be leaking somewhere. The spark plugs should all color about the same. Correct me if I'm wrong.

I just adjusted the idle mixture nut on the bottom.

Thats what I was saying it has a header/intake leak I need to replace gasket. Nice work on your car by the way :classic:

Thanks :classic:

Yeah replace the gasket first, see what happens. Make sure the mixture screws on both carbs are turned out equally.

Fix the leak, Check your valves, Check your timing! Then lose the accel wires. Can't trust them. You need to do what Travelin man said. Sure up all systems before you try to read the plugs. Unleaded fuels DOES make them very hard to read. Better off with the AF gauge.
