A little background might help.
Timeing any engine with any components starts the same way. If the components are compatible with the engine. You have to get #1 piston to top dead center or to the where the engine is desigined to fire or cause the #1 spark plug to spark causeing combustion. The cam is designed to have both the intake and exaust valves to be closed at this point. The fireing order is determined by when this happens at each piston. Getting the Allis C to this point can be done by taking out #1 spark plug (plug closest to the radiator) and cranking the engine over by hand slowly while holding your thumb over the plug hole in the block untill you start to feel pressure. Watch the inspection hole (in the center of the clutch housing on the left side) for the line scribed on the flywheel marked FIRE, this line should be centered. This will have to be done by moveing the flywheel 1/2" at a time with the crank. Its bump the crank then look in the inspection hole unless you have 4' arms or someone to help. With the mag inplace on the engine and covers off rotate the mag back and forth untill the points are closed but just ready to open.
Replace the cover and set the rotor to point to where #1 plug wire terminal will be. There should be a arrow on the cap.
but on a mag this would be the terminal to the top next to the block, #2 terminal would be to the top and away from the block or closest to you at the top. #4 terminal would be closest to you at the bottom of the cap, #3 terminal would be at the bottom of the cap next to the block.

It is sometimes used so well you can't tell its there and other times used as a sloppy quick fix. Finding where and how it can be used correctly is key to whether you are using it as an "inelegant hack" or an integral solution to difficult and expens
