  • I took the cover off to check the timing.
    The good news is that the cams are turning.
    I have no marks on the outside of the sprockets. Only inside.
    At TDC like this.


    There is a little slack in the chain but it’s in good condition.

    • Good news the cams turn! I'm not seeing the marks (circles) though... Maybe ABY is different and someone will come along and clear things up but photo of cam sprocket marks on my 7a are like this. Facing each other and level with top edge of head. Yours are away from each other? ​​​​​​

      • I think you might be 180 degrees out. Do another turn on the crank so the circles face each other then see if the o mark on flywheel is lining up with cutout on gearbox. I think you might be at bottom dead centre on number 1 in your pic...

        • Correct me if I’m wrong but your cams are out of timing both the marks on the back of the cams should be gaceing each other down the centre of the head

          • Yes, turn the crank another 180 (in the normal direction of rotation so you take up any backlash ) and double check all the marks again.
            Looks like it’s ok though

            • I’m sure something doesn’t look right about that pic. If the timing is out 180 shouldn’t the the hall sender plate hole be at the top.

              • And does the timing marks line up on the same tooth on the front and on the back of the timing pulley.

                • I moved it until the two o marks were in the centre.

                  Fly wheel line is marking TDC but top pulley is not! Way off.

                  Black felt pen on the mark!

                    Only when the o marks on the sprockets are on the outside

                    • At TDC on cyl 1 all the valves on cyl 1 should be closed

                      • Yes. They are closed. And piston in cylinder 1 is at the top. Oh ****

                        • So I don't fully understand. With the two o marks on the chain sprockets in the centre next to one another indicating TDC the flywheel line is also indicating TDC, so should be good. Why is the top cambelt sprocket so far off?

                            • The only thing I could think of is that the cam pulley has sheared it's keyway and slipped
                              It's a love/hate relationship with the S2,i love it,it hates me

                              • Yes, it seems the cam sprocket has slipped a complete 180 from where it should be.
                                This means you still get the pin and the hall window lining up so the fuel pump runs.
                                But the timing is 180 out
                                This is a complete fluke of the worst kind
