Chucktv, You may have tried this already in which case ignore.
If you remove the valve cover and turn the engine so that No1 cylinder is at TDC the dots on the cam chain wheels should line up with the arrows on the adjacent camshaft bearing block. If there is a TDC mark on the flywheel it should now be seen through the window in the clutch cover. I don't know if that helps though.
Cheers gentlemen. I was trying to avoid removing the valve cover but I guess I should, at least so I can mark the 0 degree more visibly. I did mark the pin to see what would happen and I noticed as I rotated the distributor that the timing was far better to the left of the pin as you say Dave. So out of curiosity what purpose does the pin have?
