Help with plug reading.

Ok I sprayed the car with a 100 shot and shut it down. Plug is a BR7EF with 4 degrees pulled and it's in the car in my sig. I was having a hard time getting a good picture, but the ring is slightly discolored and the strap has a light tan spot going about a 1/8 inch from the end you can see the line. Let me know if I need better lighting.

Can you cut the threads off? I need to see the fuel ring at the base of the porcelain.

Timing looks good. Fuel is a little light imo. Heat range looks good.

What n2o and fuel jets?

N2O is a 52, and fuel is a 27.

I thought the color looked a little lean. I've got a whole bag of jets, I can go one step bigger.

I'd probably put a 29 in it at least.

No a 31 won't be too much. Might be a tad on the rich side but some engines like a little richer mixture. keep cutting plugs and you will know.

Just a reference point for you. This plug is years old when i first started tuning ls motors. Little rich but not bad, decent timing mark and good heat range.
