Default Evolution 7-77 radial

Good day.

I have a question. I have the Evolution 7-77 cc radial glow engine. I am almost ready for the break in procces. I have noticed a strange noise when I turn the propellor. It is a ticking sound and starts with the third revolution in other words, when I turn the propellor 7 turns the ticking sound start at the third revolution, and stops with the other revolutions. I removed the back plate and there was nothing to see, everything was oke. I checked the lash of the valves and also that was in good order. What is that sound? I think the sound comes from is inside the engine but I am not sure.

Regards, Timo Montagne .
