Here is a picture of my spark plug. They are AR135's. There is only a little bit of carbon up on the strap. Should it be almost in the middle of the strap where is starts to curve? Is this too cold or too hot? Any help would be appreciated. I am trying to get the car ready for tomorrow morning. Thanks

Can't open it, this is what I get.

"An error has occurred.

You need to post the "public" address to your pictures. The one you posted is for the owner of the album (that would be you).

I have the pictured uploaded to Webshots.com. How do I get it to here? I've never posted a picture on here before.

I hope this works. It is in the community section of webshots.

Too blurry, try setting your camera to MACRO mode (picture of flower), then both the camera and the sparkplug on a desk and press the button.

If you go to the track much you can jet it in accurately there.

Jet up a couple of sizes at a time and watch your MPH.
If you pick up MPH you are going in the right direction.

If it looses MPH go back down in size and keep your eye on it.

Make a small gain on the secondary then work on the primary,alternate back and forth,sneak up on it.

Either way stop when you get the highest MPH.With race gas you may find by backing it down one size from optimum you will keep the plugs in better shape and the car might run more consistantly.

Interesting Thrasher. You're probably right about that. But I expect the heat range and color ring readings are probably similar as well as the signs of detonation.

About my comment above...

I think that the above link will still be valid because the coloring will only effect the porcelain.

Here is a link to several links that provide PLENTY of plug reading advice.
Hope you have a lot of time to kill

Thrasher is right about the racing gas. At a 14.7:1 A/F ratio cruise on my truck (unleaded gas), the insulator is ghost white. On my Camaro, running 50% 110 and 50% 92, it's a light tan color.
