At a wall Timing marks
 

I got the build on my NA 13b done. that was easy, no problem. I spent the whole day trying to get the damn crank angle sensor set to one of the two timing marks on my front pully. Yes I know about the mark on the crank angle sensor and yes it was set, but damn it this thing just wont time in. I'm going to get the chilton in the morning. Any of you have any tech sheets on how to get this crap done that would be great

If you aligned the the marks on the CAS & the mark on the main pulley, there should be no reason to adjust it again. Make sure the engine is warm and idling under ~1100 RPM, or the ECU will advance timing.
