Bruce that doesn't work because the oil pump on an aircraft engine is
separate from the magneto drive gear. You can't get the aircraft oil pump
turning without turning the crankshaft.

Cy,

We are all here to learn...well some of us are. Do you know have the
energy to elaborate as to why? Or do you just enjoy being abrupt?

I do know the answer now because Veeduber went to the trouble to
privately email me and explain the differences between the engine
designs. You had a chance to enlighten others here on RAH. I am sure
there would have been one or two who would have appreciated a more
complete answer.

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.
