Line up the fixed pin with the first mark on the pulley.

Leave the black, flat cap on the CAS on the CAS but remove that small access plug on that black flat cap.

Loosen the CAS clamp so you can rotate the CAS by hand. Turn the CAS till you see one of the two "pointer" inside the CAS opposite the hole where the access plug was removed. Done.

I got that idea from BUMPSTART down in Auss. Seems to be a correct way of doing a visual timing on the RX without a timing light.

and since that pulley is aftermarket who knows where the marks are.
If you feel you are in the right Vicinity timing wise,and the car is running fair,then for the Hell of it,Pull the CAS again and move it one Tooth..one way or the other,and see if that fixes your issue.
I know the front pulley has marks on it.But really at this point you have already used them and thought it was close to a stock setting.Well you are close...What I am suggesting is line up that pulley,same as you did before and stab the cas one tooth one way..test.
then Try the other way.
Try Timing the car without pulley marks!.That is a real Pain in the ass,But I did it!

the problem is when i had it at -20 deg top dead center on my pulley it ran amazingly it just purred! but im not sure that it sounded good, not really sure how its supposed to sound im new at this ! ha

all i have on my CAS is Two screws holding the flat black plate on the top on there. I have an extra Pinapple Racing CAS that came with the car along with some other stuff. is it possible that i rotated the pulley too far around and its timing the wrong rotor ?
