I've seen fuel pumps go bad and leak into the engine diluting the oil. Usually the oil level goes up. the diluted oil goes past the rings easily, and fouls the plugs.
Check your vapor recovery lines, maybe something is wrong there.

Thank you David. I kind of had a feeling that the fuel pump might be the problem. I will try another pump.

if your car is fresh out of storage, check out the fuel quality, your nose knows.... bad fuel can be expensive, and can ruin several carbs (one after another)
thanks for reading this drivel
