The link is good advice. One thing to emphasize, hold the prop tightly when you are turning it over feeling for the kick or bump. I'd also suggest holding the prop blade firmly when connecting the battery to the glowplug. Occasionally the engine will spontaneously start at that point. You can get surprized and have bad things happen. I seldom use a chicken stick but usually hand flip with a heavy leather glove. The glove is not perfect protection but it will save you a lot of blood.
