Why your 4 stroke engine only runs when you spay gasoline in the carburetor?

If your four-stroke engine only runs when you spray gasoline into the carburetor, it likely indicates a problem with the fuel delivery system. This could be due to a clogged fuel line, a malfunctioning fuel pump, or a dirty carburetor that isn't properly mixing air and fuel. Without the correct fuel-air mixture, the engine cannot sustain combustion. It's important to diagnose and fix the underlying issue to ensure proper engine operation.
