Your thoughts on this plug

Just wondering what your thoughts are on what this spark plug is telling us as far as carb setting. It's a new plug with 450-500 miles on it.

Looks good. Aso looks like the elecrode was cut back some to get a better spark. It will have a shorter life though.
A little anti-seize on the threads and dielectric grease on the towers will be the final touches. Torque with the washers installed.

The electrode was not cut back.

That plug is close to textbook perfect. Now, check the other 7 to make sure no problems.

I like the NGK's.
