You're right -- having the car running without a driver isn't too sharp and
idea. Local (metro D.C. in this case) procedure is to have the driver blip
the throttle from inside the car -- I've run in other places with similar
procedures. This tests the entire throttle linkage, not just the top --
considering I own a car (not the Prelude) recalled for possible kinks in the
throttle cable, this seems to be a good idea. No hands in the engine.
Local supps also require at least the driver's floor mat be removed, which
eliminates problems with the pedal hanging up. The couple of times I've
done F500s, clearing a space in front of the driver and having him blip the
engine did the trick -- the car doesn't move that much.
You could do this with the engine off, but IMO, engine on is better -- you
get the additional input from hearing the engine spool up and down. For
carburetted cars, pumping the throttle with the engine off is a bad idea
anyhow -- at best, it floods the engine, at worst, it risks a carburetor
fire on start up.
