Gas runs out of the carb in snowblower

I have a real stumper for you . I have a 30 year old Ariens HS 50 Snow King snowblower that I have been fixing up all summer. It has a 5 hp tecumseh engine. At first , I rebuilt the Carb , and then I ended up replacing the Carb . It starts , it runs , it works fine , BUT , when it sits , gas runs out of the Carb and onto the floor. The whole carb is wet. I replaced the fuel line and clamps . That is not leaking , the fuel tank is not leaking. Sometimes it takes a week for the gas to run out , and sometimes it takes two or three weeks , but it will run out sooner or later. My next guess is the gas cap is not venting properly.....after all , it is 30 years old...... What do you think ?????? Regards , Username612

My guess is the float in the carb has become a sinker, remove it and shake to see if it is full of fuel or set it in a glass of water to see if it sinks. Have a good one. Geo

No , I don't think the float has become a sinker because it would be doing it all the time. I did take it apart , The brand new carb , just to see and it does float. Any other gusses ?????? Username 612

The needle seat is not sealing properly to shut off the gas so the float height might need adjusted, I think it should be 9/64" when setting upside down. Have a good one. Geo
