carb leaking after cleaning

I have a Craftsman snowblower with a 6.0 hp Briggs & Stratton. I cleaned carburator and put back on. It started right up and ran but after shutting it off, it started leaking gas out of the little ports of the carburator. What causes this? Thanks!!

The carb needs a good looking at, sounds like the float valve seems not to be closing as it should. All the jets and openings should be cleaned.

Agree with Sid, float inlet valve is not closing or sealing.

Sounds like it's leaking from too much fuel. If the float is set too high the fuel level will be too high and it will leak. If the needle wasn't attached to the float properly it might not be able to seat allowing too much fuel into the bowl and it will leak or the needle and or seat might be defective or damaged and not sealing which will also let in too much fuel and it'll leak.


Make sure the windows are up before the snow plow goes by !!
