Holley Idle mixture screws non responsive?

I am not 100% sure on the timing right now I have been messing with it so much I will need to go back and check it all out. But I know its at 14* plus mechanical and vacuum advance.

I am gonna lock it in at 18*, pull the carb and check the transition slot and adjust the secondaries if necessary.

Does the vacuum reading sound about right for this combo? I thought it was kinda low.
