Washed a house today. The motor ran Mint. Shut it down at the end of the job and went to start it again and it won't pull. It recoils bad. Took the spark plug out and it pulls. The motor has about a 100 hrs on it, Is this a valve problem?

I'm assuming you have the trigger open when trying to start? My guys always have a hard time starting PW's cause pump is under pressure and they break the coil and cord. Dumb azz's
Course I know your not Art!

Hey i know a little about small engines! (Emphasis on 'a little', hah.)
Was looking up the GX390, because that's the engine i have on my pressure washer, and ran across this thread. Did you ever determine the cause Art?
A starter rope recoiling hard is often a timing issue, and a common cause is a sheared flywheel key. What happens is that the engine fires at the wrong time and pushes the piston back down the opposite direction that you are pulling, which causes the rope to yank back violently.
Here is a video that discusses how a bad flywheel key or camshaft causes this condition, as well as an article that discusses the flywheel key specifically :
Here is a question someone asked specifically about this condition on a GX390. They discuss several other things that can cause it (bad coil, flywheel key, camshaft). In his case, it looks like it was the camshaft, but he never returned to confirm.
