Indeed, which makes it all the more important on those occasions when you *do* have to pull the propellor through - those of us with radials in particular - to act in the same way as you would if you were trying to swing the prop for a start. High compression engines can brain you with a prop blade without any internal combustion being required - even in the complete absence of fuel, or HT leads being connected to spark plugs - luckily, on that occasion the blade missed my head by miles - did deliver a glancing blow to the b0llocks though. Not the sort of lesson you forget.
I was there when our mutual Uncle was pulling the prop through on his previous S2 which decided to fire a couple of cylinders - he might have short legs, but by God he can move fast when required....almost a blur, in fact.
