Re: How in heck does this thing work? (Nu rex)
Why must you time the engine perfect?
Gap the points correctly. The starting point is, timing pin in dimple, distributor body on distributor base, then move the spark lever until the upper plate arm just touches the distributor body. Then by some means of your choice adjust the cam to the proper position. The distributor body can be off or on depending what method you use while timing. The reason you start with the distributor body on is to get the upper plate arm in the correct position.
If the body is off when setting the spark lever, you could start out being to retarded. Use the body as a limit stop, not the steering column.
I like using a light across the points. When I pull the spark lever down 2-3 notches the light comes on. There is plenty of movement in the spark lever to make up for a few degrees of miss timing.
A properly timed Model A should never be run with spark lever all the way down.
