Holly carb help

I still fail to see how the power valve can affect idle. It's on the power circuit. But I won't argue it here. Don't wanna sidetrack. Yall carry on.
LOL Need more coffee. Was answering about locked timing at 36.

Power valve number would not be an issue in a properly set up carb.
Power valve damaged would allow fuel from the bowl to get pulled straight into the intake. Also if the PV gaskets are damaged. I'm sure you've seen both.
