Re: mercury kg-4 questions

It appears to have had the throttle advance clamped in place and it had a throttle hooked up at one point (the bracket opposite the fuel shut off). The fly wheel nut comes off with a special tool or I used an old clamp that slides on a bar with a screw to tighten and they seem to come off with that. You could also try a large crescent wrench. Under the mag plate should be some screws that clamp the mag plate that you may be able to unscrew to take off some tension. But I would not force anything until you pull the flywheel and make sure everything is clean and ready to move.
