Put crank at TDC of Compression Stroke (if valve covers are off this easy to see when intake valve has rotated and closed)

If everthing is back together you will remove #1 spark plug and put wodden dowel or long straw into cylinder and rotate engine till it tops out and TDC mark on crank.

Then with #1 spark terminal marked on Distrib housing. Put distrib back in and note center of rotor blade aligned with mark. If not aligned, lift out distrib half way till you can rotate the rotor one nothch on the gear teeth and slide all the way back down and recheck. Keep doing this one tooth at a time till you get he rotor blade centered on the #1 spark terminal.

Then set distrib half way on it adjustment travel and tighten down. Recheck by rotationg crank and note if rotor alwys aligns with #1 termianl on cap.
