Liquid does not compress at all, But I mainly wanted to comment on something else...

First, don't have the glow plug igniter connected when you turn by hand.
Second, you don't need to remove the plug. Just turn the plane so the engine is sitting with the muffler down and turn the prop backward, any excess fuel will run out of the muffler port. (in the case of a 4-stroke, just turning backward should clear the fuel back into the carb).
