RE: YS 160 Piston Damage

I think you have missed the point completely. By turning the engine before igniting the plug you are charging the cylinder with new fuel and in effect flooding it.
When an engine is stopped by closing the throttle (cutting off the air) once the carburettor is returned to the idle position from closed, the engine is in perfect condition to start again, so cut off the fuel immediately after the engine stops, and only open again seconds before the restart, connect the glow and turn the engine, it will start. Every time without any kick.
