lining up the C.A.S. for timing

alright so i finally got off my lazy *** and decided to time the car and see if that helped. the leading timing mark was in inch out time!!! so i got it straight and it ran beautifully. and when tightening up the nut to hold the CAS down it snapped the stud. so i had to pull out the CAS. i lined up the first timing mark (leading) at TDC. pulled the CAS out, and looked in the FSM wich isnt vary detailed on it. all it says is to "match the mating mark and instal the crank angle sensor on the front housing". and i was guessing the little raised ridge on the bottom of the CAS body, right ubove the gear was the mark, and the hole thats in the gear is the other makr you line up. so i lined up the hole in the gear with the little raised line on the CAS body. tooke it out for a drive and it doesnt really buck... but just... well sounds like a car out of time. what the hell. oh and yes i secured the CAS back down with some JB weld, my best freind. and it didnt move one bit. the timing mark is dead on with the timing light set at 5degress advance and clip on leading #1 coil. but it runs like **** like its out of time!!!?? did i put the CAS in wrong?

GIVE THAT MAN A PRIZE!!!!!!

Yep, you have to do that or the timing will be all over the place as the ECU adjusts for RPM and vaccuum changes
