Thanks for looking,
I have an OEM 2bbl Carter on top of my 383, and I recently rebuilt it.. I think I made a mistake somehow, because the car will start and run fine until it's hot, then it balks and quits if I let it down to idle...

When it has stopped, I can smell gas, I pulled the air cleaner, and can see fuel dripping out around the lower throttle shaft onto the manifold, I can look into the venturi's and see gas dripping rapidly, like spilling, from the little brass pipe/nozzles in the center of both venturi's,

..so I think something that is supposed to stop gas from flowing freely (check valve anywhere?).. isn't working.. I mean, the engine is stopped and it's just emptying the float bowl.?!

If I wait 15 minutes, prop open the lower butterfly valves and let the visible cloud of gas vapor dissipate, and, I can get the car to fire up by stepping full throttle on the pedal.. then it'll last me another 10 minutes to limp home before it quits again..

Maybe there is also an extreme rich adjustment problem? ...but this is the OEM carb for the car.. I didn't think these OEM Carters had an external mixture setting.. other than the idle bypass air screw..

So I mostly suspect some kind of internal check valve problem

I'll rebuild it again, but I'm hoping you all might clue me in on what I might have done wrong so I don't repeat it... ?

Thanks,
