Great stuff, this method of bouncing off combustion (not compression) is the only way to start some engines eg. the little COX -049 which runs either direction due to it's reed valve. If you flick the prop anti-clock it fires up clockwise, so you have to flick the prop the opposite way. This video proves the skill of the opperator to understand the engine and also proves the quality of OS carbs when set up perfectly.
Yup , thats how you should start those engines. Bounce it off compression . It should then bounce and start the correct way. Mine is getting there (brand new engine) so it's not broken it yet but it'S getting easier and easier to get her started that way. I've also noticed using a starter sometimes unscrews the prop because too much compression. Great engine.

I have an OS 15LA with a very small 8x4 prop which has barely any momentum, will this still work?
