Ok, an elementary question here but its easier to poll the board then dig thru the textbook.

On an 82 931, do I set the cam timing mark to correspond with the "Z" or the "0" on the flywheel mark?

Seems to me I set it to the "Z".....

Thanks as always....

Z1 is correct, the O is for ignition timing.

Thanks Paul, call it a middle age brain fart......

So did you buy new followers for that new cam instead of taking a winter vacation?

That's the next purchase - ouch

By the way, here's another elementary question - the tech manual isn't clear on this point. WHen adjusting the valve clearance, is the cam lobe pointing up or at 9:00? The manual says pointing up but the picture shous the cam at 9:00. Hence my confusion

There is probably a pretty large area of the base circle with zero lift (and hence a big margin for error), but I would try to have the lobe at 180 degrees from the follower to make the adjustment.

If you haven't bought new followers yet, what are you up to today?
