Todays battle ended in a draw.  She started on her own gas finally, after I added another 6 gallons, and then after running a few seconds began barfing gas out the vent tube, and this little port at the front of the carb that's covered with a little rubber flapper.  Carb's dead isn't it?

Not necessarily. The vent tube and the anti-vapor lock rubber gasketed vent, 99.9perent chance is the needle valve is stuck, first closed, now open. Pull the top of the carb off, which is easy, check the float which should be brass (don't touch with your bare fingers if it is the phenolic black one, finger oils will make them sink faster). Pull the float off, pull the needle out, verify it moves freely by itself (the needle in its brass housing, rubber tip intact, all that stuff). From there, verify the float does float in gas or water (they will dry off easily enough), then reattach the float, needle and pin, and simply turn the top over so the float is on top. The seam should be even with the gasket surface, the top of the float should not touch the inside of the cover, a quarter of an inch would be a safe gap between the two, and reinstall. I bet, since she did start on her own, the needle stuck and then gas simply poured in without being able to have the float get past whatever stiffness is within that needle. Since she has flooded this way, the gasket should be good  enough to not rip, and it will at least get you home safely.dana442011-12-21 21:12:54

Oh yeah. . .Come armed with a can or 2+2 carb cleaner or a real good one.  Seek out the best.  When you get the the float working right, shoot some carb cleaner down the vent

Ok, just to be sure, the vent is in the center of the carb, near the air cleaner stud, correct?

Fom what I can tell, it's a Carter BBD.  I should have read the carb tag.  I always did have a problem with the car before I sold it.  In the summer, after it sat about 4 hours in the heat, it wouldn't start to save it's life.  Finally after cranking on it repeatedly, it would start.  Perhaps this carb needs rebuilt?  If so, I'm a bit sunk, this is something I've never gotten into.

If you can find a heat shield for the carb, that helps too.

What's the little rubber flapper up front for?

What it does is allows the gas in the bowl to vent when it is bubbling during vaporlock conditions, but sealed so things can't get in with the throttle closed, so it is just a vent or purge, no big deal. They can be plugged or fixed to seal constant, which is what I did with my 6pac setup.  The fact fuel came out it and the vent tube is too much fuel, sunk float, or stuck/sticking fuel level needle, or sticking higher than capable fuel pressure, which I doubt is the problem with a stock fuel pump, just doesn't happen.

Ok, the Newport wins this round also, but I gained ground!  We no longer barf gas all over hell, but, she doesn't like starting much at all, and when she finally does, she runs really well for 5-10 seconds, and then acts like she's out of fuel.  I thinking the fuel bowl isn't filling all the time, and she dies when she empties it.  Perhaps the carb's acting up, or the fuel pump, or maybe it just needs a fuel filter.  Opinions?
