not with the type that i am talking about it won't. basically, when you pull the trigger something inside spins up until it has a load of momentum. it is then released onto the output shaft with such a whack that it shocks the bolt undone. takes a few goes, but it works.

there are 2 types of wazz gun, maybe the one that you will try is the other type that will just try and turn the nut/bolt at the same time as shocking it. either way, with the inertia of the flywheel and the friction of the pistons and stuff, the crank will probably not turn.
