Your welcome. Sometimes you can't trust the engine number that is stamped on the engine either.

Hello, how do I understand that 161QML is 200cc? I mean how do you decode the "161QML" to get "200cc"?

Way too late... but, for posterity...
(since, I've got one of these 161QML engines too)

This helps decipher engine codes:

FWIW... Apparently, the 161QML is 'physically' ~189cc, according to this post:
