the points are located in side the dist under the rotor. if you look at the dist cap you'll see a hole in the side with a metal cover. the adjustment screw for the points is located behind this. if you have access to a dwell meter hook it up to the neg side of the coil and turn the adj screw until you get 28deg on the 8 cyl scale. if you don't have a dwell meter than remove the dist cap and turn the engine until you see the points open to the widest position. you should be just able to slide a .016" feeler guage in between the contacts. this will be close to the proper dwell setting. then set the timing to the proper spec.
dwell is the amount of time the points stay closed.
top dead center is the spot in the pistons rotation where it actually stops going up and starts to go back down into the cyl.
ign timing is the point in this cycle that the spark plug fires to ignite the fuel.[ usually before tdc]
hopefully this helps you understand a little more.
a motor manual would be a good investment for a beginner as it will explain the basic maintenance procedures in steps. it will also tell you what to set your plug gap, ign timing, point gap, ect at. mike
