Yes it needs to rotate. Take the distributor in your hand, does it turn in either direction? Does it return when you let go?

It should turn clockwise upon revving from idle.

I have had them fairly stuck before. Working them and cleaning stuff might loosen it up. Make sure you don't have a vacuum leak as well. But, if the engine runs so good you might not have a leak.
