Carburetor is leaking gas. What could be the problems? Gasket?

Some possibilities for bowl type carburetors in no particular order:

• Bowl/carburetor body gasket has failed.
• Float could be stuck and failing to shutoff gas flow. Sometimes sharply but gently whacking side of bowl will fix this without taking bowl off.
• Float is defective and failing to float which causes gas flow to not be shut off once bowl fills.
• The seal on the stem attached to the float is defective which would also cause the gas to not be shutoff once bowl fills.
• Carburetor body is cracked.
• Bowl drain seal is defective.

The exact location the carburetor is leaking from is indicative of the problem. Leakage from around the choke and throttle butterflies can indicate a fuel shutoff problem. Posting your specific equipment model may also yield more precise responses for the carburetor model you have.

More than likely, the fuel valve is sticking because unstabilized fuel was left in the snowblower for sometime.

You have to get some carb cleaner into the fuel line at the carb somehow. If your lucky you might free the valve.

Then, mix something like seafoam carb cleaner with the gas and run for a bit. Use a small amount of gas mixed with the seafoam carb cleaner and let it run out before using new gas.
