Holley/Demon Carb stumble

I had the day off and wasn't on call, so i slipped out to the track and did some testing. no timing equipment up at the track. just the track surface to make some stomps on. If i just need one i will sneak out the back road. but i wanted to string a bunch of them together.

This is the the same plug i posted above. pulled it off the trailer and let it idle, nothing else until it was up to 180 degrees(were my cooling fan turns on. shut it down to Pull this old plug out for a new one

With the new plug install, i made a stomp down the track and clean killed as best i could. pulled plug out.

2nt and 3d stomp when i pulled the plug i cut the picture. didn't figure this out until i got home.
The last one is hot lapping! I did 3 runs back to back and then clean kill it at the top end to take these pictures
