Compression test showed from top to bottom:<br />85<br />120<br />120<br />Any suggestions on cause and possible cure, short of a tear down?

Pull the head, and take a look at the cylinder wall's. It seem's people want to shy away from this, and will suggest a de-carb. That spray can will only take you so far. Take a look inside, then you know!
