did you replaced the spark plug wires? your firing order might not be right...it goes: 1 3 4 2. by black soot you mean oily or chimney soot?
if your filter was nasty you night have a deteriorated in-tank fuel pump mesh filter and your in-tank pump may be nasty as well....hell both pumps...
your fuel pressure regulator may be the culprit....

Yes, the condition is indeed indicative of a rich running condition. Not enough air can cause engines to run rich. When is the last time the air filter was changed? If it's not just totally filthy, the LH2.4 injection should be able to compensate. If the air filter is ok, then most likely you are going to find it is time to spend a bit of money and tlc. Most likely the oxygen sensor is bad. It samples the byproducts of combustion and tell the ecu to richen or lean the mixture. Obvious that isn't happening. Check your firing order on the plugs to humor us please. You have no idea how often they get mixed up either at the d cap or at the plug. It happens to all of us. Check/change the distributor cap and rotor. You AirMassMeter could be dirty/failing as well. Before you go too far...remove the oil filler cap and look in it while someone cranks the engine. If the cam doesn't turn then your timing belt is broken...when they are old, they will break at the slightest provocation.

If your 240 is like my 1987 740, just because you get fuel at the fuel rail does not mean the main fuel pump still works. The in-tank pump will still deliver fuel even though the main fuel pump is dead. The car will not start with a dead main fuel pump. Go to www.stepbystepvolvo.com for free 740 no-start guide; it may help in your case.
Good luck!
