haha, well, I'm a dental lab technician, used to work in a machine shop. On the Poulan 46, I first turned the flywheel on my lathe, then removed the rest of the fins with a moto-tool and a pear shaped burr, smoothed it up a little with a heatless stone (non-clogging), then spent the rest of the Saturday morning sanding it with a black&decker detail sander. shine it up a little with an sos pad. then check the balance on your high point balancer. lots of work, but you can make the stock flywheel look like a custom piece.
