I think that I'll get at least two so I can have one in the tool pouch of the cars we drive the most. When I first heard about it I thought it was for electronic ignition. After reading what some have said I can see that it would make setting the timing easier in regards to the backlash. I agree that you need full advance and retard movement in the cap body, That should be understood in any case. If the points are set correctly and the points cam is of correct manufacture the points will be in the correct position if the rotor tip is correctly pointed when the timing pin drops in place. This is just common sense to me. I really don't see where it makes any difference where the spark lever is. If the rotor tip is pointing in the correct position that is what matters. I guess they could also add things to look for when setting the timing like make sure that the ignition was turned off, the gas tank had fuel and check the oil. Things like that are only common sence Complicated instructions and backlash is what cause most to be running with retarded timing. In the day when the model A was new and the owners manual was printed, model A's didn't have backlash rotation in the distributor shaft. I think the thing about spark lever position and watching for the points was just an added precaution. I still say that if the rotor is aimed correctly the points will be just right if they are gapped correctly. Also points setting does effect timing but that doesn't mean that the distributor cam needs to be moved each time that the points need to be re set. The model A is a simple automobile dwell meters and timing lights really don't apply to the model A distributor. When I hear sombody talking about degrees it is obvious to me that they are trying to impress and their timing is usually way retarded and their model A is probably overheating and lacking power.
