Here comes another one!

[kmcnelis@nmsu.edu]

New crank sprocket has no registration mark on it.  How can I be sure to line 
it up right?  The old one had the keyway right under a tooth, and the mark was 
about a tooth and 2/3s away.  The new one has the keyway right under 
a "trough".  Can I measure the angle of on the old one fron the keyway to the 
registration mark, then transfer that angle to the new one?

Other suggestions?
