Anyone want to read a set of plugs?

Trying to get a second or thrid opinion on the mixture.

They look just like mine and my 78 is running fine. I also have three manuals, one for the B, one for the Ford and one for the Buick. Those pix also look like your plugs.

It appears to me that these are two different sets of plugs with the top set being just a bit too hot for the type of driving they suggest. However, the mixture is about right maybe just a tad lean.--Fwiw---Keoke

I agree with Keoke. A fuzz lean for an MGB. On the agenda for today is a plug cut on a fresh TR250 engine with 2 inch SU's. If they look like those in the pic I will be happy.

Your's look OK to me...too lean for racing, but fine for street.
Remember that plugs are ususually read after a "plug cut", where you run the car at high speed, put it in neutral, shut it off and coast to a halt. Then pull the plugs right there and read them. To get good readings, you should never allow the car to idle for more than a few secondes before removing them.
Here's a good page on plug reading.

I think that's just a trick of the light. They look fine to me!

If I had those plugs in one of my drivers, I wouldn't worry about them.

 

[Nunyas]

I have to agree with everyone else. They all look good, but possibly just a hair on the lean side of things.

Today's fuels usually result in a darker plug than desired. I'd say those look perfect for 30 years ago but a touch lean for today.
