Carb issues???? Help 291 desoto (2x2 set-up)

I have a 291 Desoto Hemi which recently ran for the first time (after sitting for a few years). I was last told that the motor had 35,000 on a recent rebuild. So after getting it going the motor ran pretty decent for about a half an hour. I turned it off and once I tried to re-start, the engine was seized. Turned out I had thrown a bearing. So I had a local shop (that knows Hemi's) rebuild the entire top and bottom half.

<O</ONow for some reason I cannot get enough fuel to the motor to keep it running. The tank is clear, the fuel line is not obstructed, the fuel block between carbs is clear, and I replaced the electronic fuel pump with an upgraded one. I have a 2x2 Edmunds intake with 2 brand new (3 years ago - but never ran) <ST1rochester</ST1 dual jet 2bbl carbs. I can see that the front carb sprays fuel better than the rear. I am frustrated because the motor sprayed fuel perfectly fine before I tore the motor out and had it rebuilt. I kept the intake and set-up at my garage, so I know nothing was changed. The motor will run if I spray starting fluid, but only burn up what starting fluid I put in then stop. I am thinking maybe the floats on the carbs may be stuck? Any insight or help would be greatly appreciated. Thanks guys.<O</O

 

Sounds like the insides of the carbs are gummed from sitting with old gas in them.

 

Take apart, clean, put in new gaskets, be sure to double check float level. Every place you see a hole, shoot some spray carb cleaner through it and see that it comes out someplace, or two someplaces in the barrels...
If possible on your manifold, block off one carb with a simple gasket missing the big holes, get car running on each of the carbs as singles. THEN it's time to figgerout getting tuning and linkage right.
