If I recall correctly the cowl screws go into arubber expansion nut. You can reach under the cowl from the center (battery opening) and hold the nut to unscrew it, or just pull it out without unscrewing anything. The rubber expansion nut does not fit tightly into the body, and if it is spinning it needs to be replaced anyway, just yank it out. It should just pull straight up with minimal force. I don't even bother with the screws anymore, I consider the rubber expansion nut a plug, and just press it into the correct opening when I remove/install the cowl.
