who can talk about afr and ignition from pics of spark plugs?
How long have those plugs been in? Can you get a better clearer shot of the last photo? Mostly of the ground strap. If these are old plugs that have been in the car for 5000 miles+ then, go get a fresh set and do a couple WOT pulls on them then take a picture.
Its hard to read old plugs.. get some new ones in and run it for about 50 miles. Do a WOT pass, shut down your can and read/ take pics of the plugs.
Fixed.
Shutting it down at WOT will give you what happened in the cylinder at the time of shutdown. So make sure you shutdown at WOT otherwise looking at them is pointless unless you want to see how it is idling.
I also say u need a colder plug and take away some timing.
Brand new plugs and a wot shut down will show better results but overall colder and less timing.

If you are using a digital camera, get someone to show you how to set the zoom to MACRO it will make taking close ups 100X easier.
I would say that its a little lean though, hard to read the timing until you adjust the fuel. it looks alright now, but it will change with the addition of fuel. Give it a couple % more fuel and try again.

This is what I go by any time I have to read plugs.
How to read a spark plug
Think is it's only really good for full pulls on a track or dyno. Driving around makes it a little harder to be specific. I try to make a run and at the end of the pull kill the engine and leave the throttle wide open. That way you will get a more reliable read off the plugs. Make sure if you try this that your on a track or a wide closed off road with no traffic and some extra stopping room.
