I thought carbs made a sucking sound normally...

yup......

What you can do is use a spray bottle of water and spray around the area that you think it is sucking from while the engine is running.

If the sucking stops then you can narrow down where it is. I bet it's between the carb and manifold.

Of course this only will work on small leaks.

Actually carb cleaner is easier to use.

Spray just a small amount using that long red straw to aim it just right. If the engine revs a little higher, you've got a vacuum leak. If it doesn't, you don't.

Vacuum sucks.

the car runs fine, I have had it for about 7 months now and it never made any noise like that before. I will try the carb cleaner.THANKS
