1970 280SEL smoking probs

Hi - I just bought a 1970 280sel fuel injected Benz and when you apply the brakes it smokes and when you accelerate it smokes but thats the only time. It faintly smells like gas and when you turn her off it keeps going for a second. What do you all think is wrong. and what should the plugs be gapped at?
Thanks
Jennifer

If you let up on the accelerator at highway speeds (without hitting the brakes), does it smoke? If so, this is a timing issue. If it smokes at acceleration, then I think again that you have a timing issue. At the very least, I'd check the timing first and then go from there ...
