If the bearings *are* phospor bronze bushes, then they should be 'loaded'
with oil by placing the bearing into hot engine oil for 1 hour +. The
phosphor bronze is porous, and absorbs oil.

A standard high temperature grease (e.g. Castrol LM) will be fine for this
application.  The bearings (usualy phosphor bronze bushes) have no real side
loads on a contactless igntion system.  As you say, the lower bearing is
often lubricated by engine oil.
