yeah, just unscrew them. maybe take the carbs off the engine, or at least stuff rags down the throats, you'll likely break the screws in half, and you don't want bits of metal ending up inside the motor
i always ran a rich idle, and had high intake velocity, so never needed a choke. i took mine off too
there will be almost no difference in anything, if you can't be bothered, you may as well just jam the choke linkage open with a piece of wire or a spring and leave it at that
