lendusaquid, thanks for that, unfortunately i need a genuine lister pic as the marks on the idler are different. My idler has 2 dots on the top of 2 of the teeth. I need too know which cam tooth goes between those marks. All in an effort to avoid dismantling again to adjust cam timing at a later stage.
Having said that if your crank is at Bdc for this cam position that may be enough info for me, i will take a better look tomorrow, thanks again.
