I'm doing my first valve adjustment on this new to me WR.


Let's call the setting in the first two pics position 'A' The punch marks on the cam sprockets look more correct to my untrained eye, but the cam lobes look like they aren't positioned correctly.






In position 'B' I have retarded the intake cam one tooth. The punch marks look incorrect but the cam lobes are more symettrical.




Flywheel is at the 'I' in 'HI'.


So what gives? Which is the right way? Is my timing chain stretched?

The more I think about this the more I am tempted to replace the timing chain here. Does anyone have the correct flywheel pull that they would be willing to lend?
