Dude, it takes twice as long to do a pressure test on a carburated engine as it does to do a flow test. No tester needed. Just cut the top of a pop bottle, clean it out and you have yourself all the tester you need.
I have been tuning carburated engines for over 20 years. I own 6 of them right now and I am the only person that works on my vehicles. I am a michigan cerified master auto mechanic. I also have the 9th certification which is "pre-'73 vehicles".
I have custom built many carburators that outperform anything you can buy. I am not one of those feable minded people that say "holley carbs are junk" I know better.
On a fuel injected vehicle you start with fuel pressure then test flow second as it is harder to test flow then pressure.
