Slow return to idle often means a vacuum leak.  Have you tested for this yet? It's a very easy/cheap test.

Just spray carb cleaner, starter fluid, propane or something similar (I've heard that wd-40 even works) around the carb boots.  If the idle goes up when you spray in certain areas, you have a vacuum leak.
