I have an 84 cutlass supreme, has a 3.8 litre. Car seems to run fine, but I have to change the air filter to often. It has fuel on it. I don't know if the carb needs to be rebuilt or I have some other possible problem. There isn't any liquid fuel in the breather housing just in the filter. I have noticed the idle air control clicking which I haven't noticed before. Don't exactly know how to test it. Vacuum is good around 20. Timing is on. Car has about 70000 original miles. It was my mothers and sit in the garage quite a bit, my daughter drives it now so I need to get it fixed before a possible fire. Thanks.
