My exmark lawn mower seems to have started knocking slightly at startup and shutdown. The only thing I did was change the spark plug. It's pretty random. Sometimes it does it sometimes it doesn't. It lasts about 2 seconds and then goes away. The engine runs fine. Nice and smooth. It has an FJ180v kawasaki engine on it. 6hp.
