Well the drill idea is a good one, but I did'nt have a cordless drill, so I you are starting from scratch then I would still rec the dynatron. If you go with the drill method, make sure that you have one that will turn the engine fast enough. You may have an engine that starts great by hand and that does not need the extra torque of the drill. I'm just saying that some of the engines like mine can be a little more temperamental than others, better to have to much power to turn it over than not enough. Best of luck on your project let us know how it turns out and what you decided to do.
