what one do i use for setting timing. are they set to factory marks? i dont have a oem pully around. any one have a quick answer?

 

I have not seen an ATI up close. Does it have just a few lines like a stock balancer, or is it numbered. You could do the screwdriver in the number one cylinder trick.

 

I "believe" the mark farthest counter-clockwise is TDC, I theorize that the remaining tick marks are at 4*, then 2* intervals from there, but they seems to be a bit off from the factory marks on the timing belt cover

 

I re-marked my stock one to double check when i built my motor... just put it to TDC and marked it with white out. I always use the timing guns that allow you to set the timing you want on the gun so it offsets it and always refrences TDC on the pulley... that way you ONLY need the TDC mark.

 

yeah I put it to tdc and figured it out
