OTOH, there's some risk that with
a prop chain, the engine could be accidentally started if
the prop is bumped or repositioned by a third party and the
mag was bumped on or failed. In the Champ, it's a
non-locking mag with a fairly large paddle lever. Beyond
that, I just don't like fooling around with the prop until
I'm absolutely ready to start.

Exactly the reason that Aviation Explorers, working at OSH assisting pilots
with homebuilt parking and retrieval are absolutely forbidden to push or
pull on a prop.

Everyone keep that in mind, in the homebuilt sections. If you want the
plane pushed by the prop, you will have to be the one to do it. Also, they
will ask where you want them to place their hands to push. Help them out,
if you will, please.
