When I press the accelarator a lot of black smoke come out of the exhaust, even the sparking plugs are black.I changed the carburattor but still the same. Vacum leak can be. Can you help me to check for the faults. Thanks

Do you have a check engine light and when was last tune-up? Check and test below

1. Excessive fuel pressure can be cause by restricted fuel return line

2. Defective Oxygen Sensors.

3. Leaking injectors and fuel pressure regulator.

4. Coolant temperature sensor out of calibration.

5. Restricted air intake system.
