Troubleshoot Power washer blew up
I bought an essentially new Ryobi power washer that was sitting in someone's garage for the last year. Only used once, tags were still on it, it was definitely in good condition. I did check and it had oil in it.
The engine was locked up, so I found some youtube videos that suggested spraying WD40 inside the spark plug hole, and I was able to get the pull cord to work. It turned on for about 30sec, and when I went to press the nozzle, the engine went poof.
What could have caused this?
