How recent is the rebuild? Often, an engine shop will request that you return after XXX kilometers or miles in order to re-torque several items.
Since what you describe is pretty much a process of elimination, it seems possible that a vacuum leak could be your issue. With the engine warm and running, try spraying some carb cleaner around each port, hose and connection where engine vacuum exists. If you find a change in your idle, you have found your culprit. Cheap, easy, quick and simple.
