I use a chicken stick to start all of my engines all the way from a .15 OS up to Zenoah G-26.
Nahhhh. That's misleadin. No comparison. I'd MUCH rather hand start a gas Zenoah G-26 with a built in magneto, "real" spark plug and a big 'ol 16" wood prop for leverage than an OS .40, or any glow engine for that matter.
