Putting engine back together for the second time. Could use some clarification on 90 SC. I have the no 1. on TDC compression stroke. Crank keyway is at 12 o'clock position. I have two different pieces of info for seting the crank position. My plastic crank cover shows 26deg ATC at about 12 o'clock. My balancer has a notch (.100 thick groove) at about 26deg ATC. Should this be set at the timing mark on the timing cover before installing the cam sensor. I have the cam sensor tool. Could someone explain the correct way to this. Please.....
 
cam position sensor

I think there are instructions on setting the cam position sensor on the FAQ.
