Oh, if you were thinking it was getting past the needle valve you would have gas pouring out of the carburetor where the accelerator pump linkage goes in, all over the exhaust, it MAY run, but very, very poorly. And I haven't seen one that doesn't leak a little bit, did you use new gaskets? I had one with the float DROP set to low, and when the fuel would evaporate it would stick to the bottom of the bowl and just pour gas out in streams. As someone here told me, the current fuel formulations tends to be rather sticky when it dries out. I suppose if the fuel bowl is full you could just attach the pressure gauge to the end of the line, it wouldn't run very long, but long enough for your purposes. It probably doesn't matter, if you know the pressure or not, but when I was having my trouble with gas pouring out, I was thinking I might also be getting high pressure, as it turned out I had a little tiny speck of rust in the pump, and I was just barely moving enough fuel up to get it to run and pour out all over the exhaust. It didn't put out enough pressure to make the gauge barely flutter. That may have had to do with there being virtually no resistance to flow as well, I'm not sure. Any way the rochesters are notorious for leaking. A little weeping is probably OK, but if you are leaking enough to actually get drips, I wouldn't consider that OK. But there is certainly no harm in trying to make it better.
