Ignition timing using the Nu-Rex wrench ?

After rotating the cam 2 turns clockwise and stopping when the edge of the tool contacts #4 distributor post per the instructions on the tool handle, should the rotor be pointing directly to the #1 distributor contact? I did this procedure and it almost there but is off towards the #2 contact a bit. This is my first timing attempt.
Thanks

It should look like this.

Lever position does not affect the cam position so it does not make any difference what position it is in when you set the timing.
 
Try and set the timing the way "Purdy" does it. I did it his way, then went back to Les way of doing things. Went back to the way Purdy does it and the car runs and sounds the best
. Just wanted to compare and double checking the timing while I was at it.

That's fine. It sounds like your initial timing will be a bit after TDC, but it should run. As long as the corner of the rotor metal tab is close enough for the spark to jump to the #1 pin. Did you try to start it? How did it run?

Did you first get the timing pin dropped down into the indent on the cam gear on the front of the engine? That is step 1. Then turn the wrench 2 times with the screw loose, but just dragging slightly, then tighten the screw as the wrench hits the tab.
 
If I remember reading here that tool can get you in a little bit of a problem, most likely retarded timing, I have never used one and prefer using a test light or ohm meter, the reason being that the slot for the rotor may have been cut in the wrong place in relation to the distributor cam.
 
I have proved to many people that I can set the timing closer and faster doing it like Ford suggested than you can get that krappy tool out of the tool box. Just do it like the owner's manual says to do it.
 
Hi Burt,
I have a tip which you might or might not know, seeing it is your 'first time'

When you do the clock wise turns, you must stop exactly on the correct spot. DO NOT GO BACK. If you miss it, even by a ball hair, do not go bakwards. Because the slack in gears and dissy, etc will mess you around. Just be patient and do another full cycle(2 revolutions)

I find if I use the tool, and do it the way they say, it is a little to advanced. So I just move it a bit clockwise and it seems to work best for me.
