Hi I have rebuilt a js550 and it was working fine for a month now it makes a loud skriching noise when I try to start it. I pulled it back apart and the stator and flywheel have marks like its been grinding. Then I pulled the crank out to cheak it and it looks fine if anyone knows how to fix this problem can you please write me back thanks

Put it back together and remove the spark plugs.Turn the engine by hand and see if you fell anything dragging. If not it could be your starter.Take it out and hook a battery to it and see if its making the same noises.The starter make not be jumping out as far as should.Look at the teeth on the flywheel and see if they look chewed up from the starter.
