Good news! I was able to replace the key and she fired up on the 3rd pull. I hear this strange tapping sound when the engine is running now. I may have put too much oil in it. Could this possibly be the cause of the tapping noise? Either that or something is slightly lose causing the sound. I don't want to have to tear this thing apart again especially now that it is running. Perhaps the tapping noise is normal and I am just being paranoid?
I appreciate everyone's help in getting this pressure washer back up and running!
