Honda GX390 won’t stay running

Hey guys, I just bought a pressure washer with a Honda GX390 and I’m having trouble getting it to stay running. It will idle at the lowest throttle for a minute or two and and start to sputter and will cut off. It also has a really hard time when the throttle is increased and it cuts off shortly after it’s throttled up. I have replaced the carburetor, spark plug, and changed all of the oil. Any help would be appreciated.

    Try disconnecting the pump from the engine and see if it helps...
     
    (IE, pump may be seizing up)...

    I have the same problem with my GX200. I took the pump off and it runs the same.
