Read my spark plugs please...

These are the plugs I put in after I tuned the Kfish and have ~500miles on them. Here's a close up of #1. The others look the same.

Thanks!!

LOL.

They look fine to me, maybe a bit oily. Indication of a normal plug- Looks like you tuned it well. As long as they don't get to this point

I'd say you're fine.

The first one (which was not too oily) was on right and tight. I felt 2,3,4 were not as snug. Was wondering if the oily threads were a consequence. Got them all evenly snug now.

The car came with a 292cam which I heard mixed opinions about on a Tii -- the majority say they will run lean at higher rpm with not enough fuel. So, on the lookout for whether that is the case or not. Will get a WB02 at some point.

Who knows? My #2 plug has always been super loose. These being old cars, I wouldn't put it past a tacky PO to have dislodged some threads from the hole. A 292 in a Tii does indeed make it run lean, though I read something in a roundel magazine from...81? Where a guy was restoring a 74 Verona Tii after a crash and the shop tuned the kf system to work perfect with the cam. Never heard of anybody else having the same luck, though.

What's your mpg running?

I think they're ok, or possibly a bit lean. 500 miles may be too early to tell.

Cheers,

Lots to reading spark plugs, but the above link is the light version.

I don't know how true this is but it makes for some interesting reading about

plugs. http://www.4secondsflat.com/Spark_plug_reading.html

With that said, your plugs look like their a bit hot/lean to me. You want a bit more colour on the insulator tip(white ceramic part below the electrode). White is usually an indication that your plugs are too hot or you are running lean. 500 miles is plenty to read plugs, you can see a difference in plugs evern after short distances. But I would

like a closer picture to be sure. Reading plugs is fine, but a wide band O2 sensor would be better as it could point out where in the rev-reange you are running lean.

I've always used this as a reference to read plugs.

Good info. Thanks!!

I will pull the plugs again after I run the car for a bit and do a closer look vs. this info.
