more oil during cool down and then ran it some more - all the while

oil dripping out - I'll leave it on the bench for a few days and maybe
add a few more drops before reassembling the motor into the housing.
Most of these motors with sintered bronze bearings have a felt
oil reservoir around the bearing. They can actually take a LOT
of oil, but it takes a while to soak in. I'd add a lot more
than a few drops, maybe a couple CCs per bearing. You may be
able to see enough of the felt to tell when it is getting
saturated.
