How to oil magnetos in upside down position (like on rd6)?

Just wondering how to oil them as the ones in upright position are gravity lubed with oil, how to do it on the upside down mounted ones?
The pony motors dont run much but i suppose themagneto need some oil ones in a while too.

The GV2Q Eisemann that was used on the RD6,7,8 had ball bearings on the distributor shaft and not a bushing like on the normal GV series magnetos. The RC and RT Eisemanns were also full ball bearing magnetos with no need for oil except for the impulse coupling. There are a few other visual clues to tell if you are looking at a starting engine GV2Q or a normal GV2Q with a ball bearing distributor shaft.
