I have been rebuilding an Edison-Splitdorf magneto and have a few of questions. What type of lubrication should I use on the points cam, I know I�ve seen this before but can�t find it now. I�ve heard that jewelers rouge it the best for cleaning points, what do you use? Also, what is the best way to store a magneto as to minimize magnetism loss, should the rotor be left in the neutral position? Thanks!

Mark, I use Delco distributor cam lube. While almost any grease like Lubriplate will work, one of the most important functions of that grease is to stay put & not wear off with use. It also has to stay grease like & not dry out. Regular chassis grease is not recommended due to it getting stiff when cold & not allowing the points to close. Most auto parts stores have little tubes of special distributor cam lube & some now even have a synthetic cam lube.
~To tell you the truth I use about anything that is handy to clean points [probably shouldn't though]. As a rule I just replace them [just points as I never replace a working condenser]. On your Edison-Splitdorf the points are hard to find & quite expensive so you really want to be careful cleaning them. Once cleaned they tend to oxidize again quickly. I would suggest you try an electronics tuner or contact cleaner [non abrasive], then run a piece of clean white paper through the points. If that cleans them enough to work just leave it at that, if they still won�t work use a very fine sand paper & make sure you get ALL the abrasive out from between the points. While I haven�t ever used jewelers rouge, that might work good. [get all the residue removed]
~On storing the mag? That magnet on the Edison-Splitdorf is external [not in the rotor] so just having the rotor in there will keep the magnetic flux & not allow the magnet to loose it�s magnetism. Caution: with the rotor out of the mag body put a piece of steel across the magnet or the magnet will loose it�s charge. The magnet won�t hold it�s charge long with the rotor out of the mag body�.
