Want this question answered?
there are 20 marks in a score
There are 6 marks on the crank pulley, the first red line is 5°ATDC then white TDC then 5° BTDC and so on ending with the yellow 20°. (should be set to 20° BTDC.) These should be viewed from the drivers side of the car; align the marks with the pin protruding from the front cover.
align the cams to the E & I marks on cam. You will see notches right beside them. Align the crank with key way up.
It will take you approximately 6 hours, if you keep the timing marks in place. Also, consider replacing water pump at same time, it takes about 20 minutes longer to do it as you replace the timing belt.
Pump, fuse, or fuel pump relay.
there are marks on the timing cover that remains attached to the block and there are arrows on the cams. there is a pointer down by gear on crank and a dimple on gear align these marks
looking at the timing marks from the top left to right you have 5 degrees after top dead center, then top dead center then 5 degres 10, 15 then 20 befor top dead center. the timing is 7 degrees before top dead center
With a timing light of course. Your crank pully should have 2 marks on it, the first mark is for the leading plugs and is 5 degrees AFTER top dead center (atdc) and the second mark is for trailing and is 20 degrees AFTER top dead center (atdc). Your 85 should have vacuum advance on your distributer, be sure to unplug the vacuum line and cap it off while stetting your timing. Trust me when I say, use only your timing marks, playing with your timing on rotaries causes all sorts of problems

I'm not familiar with your particular model, but most crankshafts (CS) don't have a visable timing mark on them. Today's cars use a sensor that runs by a point on the CS in order to achieve proper timing. If the timing chain gear is still on the CS then you can look here. On this gear you will notice a dot/notch on one of the teeth. When this dot/notch is at the 12:00 position, the #1 cylinder piston is at top dead center (tdc). I cannot say this applies to all engines. I always pull the sparkplug out of the #1 cylinder and double check to make sure everything agrees.
CAM or Spark? the cam has cogs, they are marked. the disty is not marked, (like all disty) but needs IGnition strobe light ($20 at HF)
Here is a link from a repair site i subscribe too. Hope it helps. It is an "Exploded" View of all the components for the timing stuff. http://www.ondemand5.com/mric/common/asp/ImageViewer.aspx?MOD=REPTIFF&MODULE_ID=1&SESSION_ID=%7BE80FA39E-8189-4681-B82C-6C58934EA88E%7D&IMAGE_GUID=90C10183&PRINT_BW=0&ARTICLE_TITLE=TIMING%20BELT%20REPLACEMENT%20-%202.0L%20&%202.3L%20-%201974-94%20EXCEPT%20PROBE&YEAR=1993&MAKE=Ford&MS_MODEL=Mustang%20LX&IMAGE_CAPTION=Fig.%201:%20Exploded%20View%20Of%20Timing%20Belt%20&%20Components%20(Typical)&COURTESYTAG=Courtesy%20of%20FORD%20MOTOR%20CO.& Most all timing marks are located on the harmonic balancer. A timing tab is located on the sheet metal that overhangs the balancer. Harmonic balancer is the lowest round device on an engine that has the belts running around it.
