Found an old points distributor lying around. Small block. No dist. numbers. So, I made a cardboard circle and put lines at 0, 5, 10, 15, and 20 degrees. Made a hole in the center and slid it on the rotor shaft. Held the bottom of the shaft in a vice, taped the housing so it didn't move, and turned the rotor. It eyeballed to ~20*. The closest I found was the specs from a 1968 318. [Initial = TDC ------ Mechanical = 36*].
Then taped a 1/2'' --- 1/4'' drive socket to the rotor shaft. It took ~ 1 inlb of torque to make the advance weights start to move [1000 engine RPM?]. It took ~ 4 inlb of torque to make the maximum advance [4000 engine RPM?]. ------- By using a degree wheel and an accurate torque wrench [zero to 10 inlbs], It may be possible to set up a distributor without tearing into it so many times. A lot of educated guessing and patience is involved. Plus keeping notes and a lot of different springs.
Just an idea I wanted to get out of my head.
