the 1988 manual won’t help you with this engine, you would need a 1989 or newer manual. The manual talks about adjusting "free play" in the cable. If there is no free play in the cable, or the cable is rusted/jammed, then the tilt cylinder valve may be held partially open which would result in the condition your report: being able to push the engine up and down, but it won’t hold/lock in any particular position. I suppose it is possible the tilt cylinder valve is rusted/jammed/corroded keeping it from closing completely as well. The theory is pretty simple here, but accessing/working on the tilt cylinder valve is a royal pain. Fortunately, you can move the engine up and down, so you should be able to access the cable connection to the tilt cylinder valve. Just be sure to prop the engine up somehow to make sure it doesn’t accidentally tilt down with your fingers trapped in there.
