Black smoke generally indicates that the fuel mixture is too rich. Changing the air filter (unless it is still wrapped in plastic) should if anything make it run less rich as the air can flow through better than with the old filter.
The high revving is more likely to be related to something else being interfered with during the course of the filter change. In an FC, I'd be checking the automatic choke connections. Take the air filter off and make sure the choke valve is closed or partially closed. Try starting the engine with the air filter left off the carburettor and see if you get the same problem.
The vibration is probably a result of cylinders not firing properly because of the over-rich mixture.
