Hi,

  I have an e-conoline van its been giving me major problems. The newest one is it is running way too rich. Ive checked the carberaator, it looked fine. My spark pluggs are black. All of them. Its smoking really bad and when I drive it its acting like the catilitic converter is clogged but it dosent have one anymore. Previous problem. So I'm really not sure what to do I dont know if I can ajust the carberator. I looked for the two screws but couldnt find any so I'm lost. Any one have any ideas?

Probable causes of an engine running rich are as follows:

1. Excessive fuel pressure can be cause by restricted fuel return line or defective fuel pressure regulator.
2. Defective Oxygen Sensors.
3. Leaking injectors and fuel pressure regulator.
4. Coolant temperature sensor out of calibration.
5. Restricted air intake system.

Your carb needle valve might not be closing or the float has a pin leak causing it to sunk or the power valve is leaking also excessive fuel pressure
