With or without the engine running? Often with the first set up, the engine needs to be running so the pump isn't pushing against a dead pressure head.

OK, where you're at will have to be good enough till you build a fire in that thing. These are single stage regulators which are foggy in response to settings till there's actually a flow thru the plumbing circuit. It doesn't take mush but it does take something.

I'm not recommending that you just hook up a hose and flow fuel into a bucket, as without the restriction to flow as posed by the carb, the settings you make would be as meaningless as the one you have with the system dead headed.

Without your engine running there is no where for the fuel to flow to, so the pressure can not drop. As long as it's not blowing past the N&S right now you'll be OK to start off with. Just make sure to check the pressure when you get the engine running.
