You work for the railway company then ? ;)

A question that you should bear in mind is what octane fuel you are using - 98 or 95 RON, as the timing is different.

I am assuming that your engine is a DX code, so using 98 RON fuel it should be timed at 6 degrees; using 95 RON it should be timed at 0 degrees. (Pus or minus 1 degree in either case)

At the moment its got some 95 in there, I was going to have a play with 0 degrees and 6 degrees once i have actually managed to find some timing marks. Which would be a nice start.
Already got the green plug out.

Ok,
Took the rocker cover up and turns out the mark we found was the right one.
According to my fancy new timing light we were runnning 38 degrees advance before, cant believe it ran like that.
Im going to make a mark on the bottom pulley tomorrow as its difficult to look straight onto the mark on the flywheel.
At least there is some progress at last.

Cheers for all the help.

i have used this method before on a polo gearbox drain plug but i just tightened two nuts onto the threads and used inner to losen then the outer to retighten works a treat

i hate having to buy special tools for things

Ok update

I took the rocker cover off and made a TDC mark on the bottom pulley and cambelt cover.

When I put the timing light on this turns out it was running at 12 degrees advanced.

We had set it up off the mark through from the flywheel and as there was only one mark there we assumed it was TDC.

Obviously it must be that the Haynes book of lies was actually right for a change in that the mark on the flywheel actually represents 6 degrees advanced.

So I have now set it back to 6 degrees advanced using my mark on the bottom pulley.

Once I get round to getting it set up properly on a CO meter and MOT'd I'll update about how well it drives like this.
