Pre-oil before first run?

The method that I have used on automotive engines is to take an old
distributor shaft with no cam gear on it. Remove the distributor from
the engine block, chuck the old shaft in a 1/2 drill, stick it down the
shaft hole until it engages the oil pump and spin away. I have been able
to develop full oil pressure on new engines that way. Would a similar
concept work on a magneto shaft hole?

Thanks to all - I have the service instruction, I was looking for
other ideas on pressurizing the system. Bought a sprayer today,
if it works I'll use it, if not I'll just cold-crank the engine.

Acro/tailwheel refresher starts tomorrow.
