1971 340 CUDA HESITATION /THERMOQUAD PROBLEM

I have a stock 1971 340 auto Cuda, the car would run fine for alittle, then start to hesitate, then cut out. I would be able to start the car right up, but it would continue to repeat this hesitation and cut out with more frequency. I was out at my friends and had to turn back, it wasn't going to make the hour and a half drive back. He offered to rebuild the carb and did with the purchase of a rebuild kit. The car now has a fast idle, smokes upon first start up and continues until the car is warmed up, but the idle doesn't fully calm down. After about a half hour of driving,it is hesitating, though not as bad as before and not cutting out.
Is this a matter of adjustment, a rebuild that isn't quite right, or time to buy a Holley and put this on the shelf ?
This car has been the most dependable car I have EVER owned and this frustrates me. I am leaning towards a Holley to save on time,grief,and for the dependability.
Any help would be GREATLY appreciated.
Thanks!

One of the best carbs IMO. No rocket science either, so if you do a little research, you should be able to cure any problems that might come with it by yourself.
