Paul,
    I may be mistaken, but did not Jon caution about Mazda not keying their
Pulleys until after they were installed?  And therefore, the timing marks
make be at different relative positions on the pulley of different engines?
Just thought I recalled that, but could be mistaken.

He just did again.

Hold on a minute. You can only bolt the pulleys on the eccentric shaft in
ONE orientation as the screw holes are differentially aligned and only
permit them to screw on in one manner (on the 89+ anyway). So you CAN'T put
the pulleys on wrong. Been there, done it-and was amazed that Mazda thought
that far ahead!

Yes on a given year. But what I think Jon is saying is; that the hole positions
for the bolts relative to top dead center vary from year to year.
As Leon pointed out the key way seems to be consistent but I don't think
you can see it with out taking the pulley hub off or maybe just the 
bolt. Unless you have made something special like a timing disk it is 
tough to be sure the key way is exactly 90 degrees off vertical with or
without the hub on there. On a piston engine one can put a dial indicator
in a spark plug hole. I don't think that works too well in a rotary.
