Holley/Demon Carb stumble

Here you go.
Just a reminder the demon only had two run on Saturday the last 4 of the day was with my proform.
The plug on the left was put in at the end of last season. The plug on the right (right side #2 plug) is vary old.
the one on the left is cyl #1 and is the one that i cut the thread off of.

If i had realized it was so ease to hacksaw of the thread i would have been doing this long ago.
