How does this plug look? Too lean? Only has a few miles on it. A good bit of running on the main. 152/42/CEL-2 jetting, 1000ft elevation and 30-60F this time of year

You need to look down toward the base of the insulator to get the reading. And if it only has a few miles on it it is hard to get a good reading. You could put a few miles on a plug with a 165 main and another with a 140 main and not see much difference. I've been there.

I tried looking down inside it and it seems to have a light black ring towards the bottom of the insulator. It's hard to tell without doing a full plug chop and actually cutting the threads off. I'm just trying to make sure I'm not too lean.
