    loosen the cam bolts and rotate the engine with the driveshaft clockwise facing forward from the back of the ski. No need to lock the cam IMO as some say to do. I used a 4 stroke impeller with a pump shaft from a 951 (same threads) to turn the driveshaft .

    actually that would advance the cam. you want to loosen the cam screws and turn the engine counter clockwise. the uppermost cam screw should be to the right of its slot in the sprocket. like this.......

    Remove the valve cover

    loosen the cam sproket bolts and completely remove one bolt
    (stuff a small rag or paper towel below the bolts in case you drop the bolt)

    bump the starter (hold throttle WOT while bumping. this will keep engine from firing)

    look at the bolt hole in the slot. keep bumping the starter until the bolt hole is to the right in the slot.

    apply blue loctite to the bolt and reinstall. remove the other two bolts, apply loc tite and reinstall. dont forget to stuff your rag below the bolts.

    well I followed the instruction on a another thread that said:

    Loosen the 3 cam sprocket bolts.

    Take the pump cone off the pump to gain access to the 12 mm allen bolt.

    Rotate the pump counter clockwise until the 2 cam sprocket bolts are all the way to the right in the slots.

    Tighten them down.

    The manual will give information on locking the cam, etc.
    guess I've got it to do again...
