It depends on what electric ignition system you have, but on my Lightspeed, I'm pretty sure it fires at TDC at start-up. Doesn't have any trouble starting my engine. I've propped an O-360, but not with 10:1 compression ratio. That might be a little tough. The O-470 carbed engine is a low compression engine and not as hard to hand prop especially with a long prop.
