I've seen people that have tried to use drills to start glow engines, but they usually don't work. The reason is that the drill doesn't spin fast enough to get the engine started. Electric starters are usually around $10-$15, so they're not that expensive at all. As a side note, I have an electric starter but I very rarely use it. I flip start all of my motors and only turn to the electric when a motor is being difficult and stubborn to start, usually when it's a bit cold outside. If done properly flip starting a glow engine is a quick, easy, and reliable way to start your motors.
