Holley/Demon Carb stumble

Ok so here is the precursor.
Installed Proform metering block with same jets and jet extension in the rear.
As i'm starting to buy in to the change in P.V set up, i pull my 4.5 and put my 6.5 P.V. back in.........had a 10.5 but not tempted to us that on just yet:)
When back and forth about the regulated pressure. altho i have been convinced that 6psi is better then 9........I set it at 9 to see how my metering block will act, compared to the Demon one's.
will make a couple laps and then drop it to 6 and probably just run it that way the rest of the day. sure i will have to raise the float, once i do this.

Started, set floats, warmed and tested........"Garage Nationals" say it's not bogging.........we will see........

In neutral revving the eng up slowly to 4000 rpm, it seam much cleaner...........Idles better, even in gear......

Fuel mixture screws are only 1/4 of a turn out for the best vacuum, which is the same as with the demon metering block.

Way to late to test it any more. loaded it on the trailer,... Going Racing Tomorrow!!!!! If i don't get called out. FINGERS CROSSED!
I'm hopeful but not holding my breath. If it don't work i will load it up on the trailer and do some testing next weekend when im not on call.

Wish me luck!!!:D
