quick and dirty version:
SPOUT connector is in the inner fender or under the MAF. unplug it (get the car warm first).
with the car off, if you can see the marks on the damper, use paint or a silver marker (what i use) to mark the degree you want (12*, 14, etc).
put the timing light on plug wire # one and time it.
loosen the hold down if you need to change it and move the dizzy till it is in time and tighten it back up. recheck, as tightening the hold down often moves the timing a degree or two.
put SPOUT connector back in. good luck.
