Can I help with engine? Make and model? Application? Have you drained the carburetor float bowl?
Symptom is lack of fuel to the engine. If carburetor has metal needle with a rubber seat in the upper passage, the rubber seat may be swelled up, from ethanol fuel. The passage will not allow enough fuel to keep engine running, the repair would be to replace the needle valve and rubber seat.
