It's probably the valve seals and possibly the valves and guides are worn out too.
P.S. Letting it run rich will eventually ruin your engine as you are constantly washing down the cylinder walls with excessive fuel, which removes the oil film protection resulting in metal to metal contact. It also dilutes your engine oil preventing it from properly lubricating the engine, which could be why you are having trouble with it smoking.
