I always check my plugs at the track right as I enter the return road, I pull over and pull one asap, thats the most accurate way to read em.
What kind of carb?What Jets?what weather conditions? also how high compression on your motor?
On a side note, Why did you cut them opened to read em? You dont have to do that..
Ran down the strip, went back to the pits and then pulled some out.
Holley carb 750 vs, 76/80 jets, humid 86 degrees, 10:1 compression or slightly under.
I cut them open so I could see the fuel ring down in there. I tried with a magnifyling glass and flashlight with no luck. I don't have an ottoscope.
