Running rich?

Hello! M104.990 1991 year. So, long story short - after buying car 4 months ago, it smelled of unburt gas/running too rich. Changed every component on fuel system (BOSCH fuel pumps, brand new, BOSCH fuel pressure regulator, BOSCH ignition coil, rotor, cap, new sparkplugs). Cleaned the million dollar MAF sensor (it runs the same with MAF disconnected or connected). New spark plugs. Engine idles smooth, no vibrations, misfires. Only thing that worries me - EXAUST SMELLS like it is running... Running rich?
