The needle valve and float is what controls the fuel into the carburetor bowl. Is the needle valve seat fully open? Or can the rubber seat be swelled up and restricting the flow? If the carburetor needle seat is all metal, it will have a rubber seat in the upper housing, This can be swollen by ethanol in the fuel . Repair would be to replace the needle valve and seat, or replace the carburetor.

The needle valve and float is fine. This was checked out too. No problem due to ethanol because I get no ethanol gas from the farm/ranch fuel dealer here. The engine will run for a short time, maybe 3-4 minutes then quit. Also, when it starts at the slow speed and then try to increase speed it will die sometimes. Also, why does it use so much gas? Oil level is correct. It does not burn oil. What I am describing is something from day one of purchase. Talked to Swisher, and Briggs/Stratton dealer about it too.

Is the carburetor choke fully opening? Not staying open? That would do the same thing, and would let it use much more fuel?
