Hmmm... if I recall correctly (its been a while), the drives will act quite
obstinate if the speed if off more than a bit. Most of the Apple drive
mechs (at least as I recall) had strobe disks on the flywheel pulley that
you can use to get the speed fairly close.

Also, the positioner mechanism on the Apple drives was quite sensitive to
the head carriage drive rails getting dirty and binding. You should check
to make sure that the carriage is free to travel across the full extent of
the guide rails easily.
