AFR Tuning: A Holley Carburetor Journey

What do you folks think of these plugs with several miles of run time, and probably only about 5 seconds of full throttle until I had to let it idle and coast into a parking lot

 

Do they all look like that........
It's too rich to me

 

Maybe try a hotter plug

 

Current jetting is 84/90. Maybe 82 is the next step?
And this is just cylinder 2

 

Also a quick hit of throttle isn't going to tell you much of anything on the plugs. Take it to the track John.....
