My carburetor started leaking even when it is not running. What are the most common solutions to fix this problem?

Were is it leaking? The exact location is critical in determining the cause or fix.

It is leaking out of the tiny hole in the bottom of the carburetor.

Leaking gas is usually a bad shut off valve or the float , hopefully it is just dirt that has made its way through the screen. The floats in the zenith carb are touchy , just a little rocking of the car will cause gas to drip out

On my 15 Baby Grand 17 490 (I sold) and 18 Model V I have had same issues the best thing I do is I have a shut off valve on them so before I shut the car off I turn the shut off valve and run some of the gas out then turn the car off. I have no issue when driving, but the float/needle and seat are very touchy on the 04 carbs
